Abstract:

AbstractOrganic–inorganic hybrid materials have received great interest in the last 10 years in the controlled drug delivery area because of their excellent biocompatible, biomimetic, and pH-sensitive properties. Biomineralization is a biomineral-inspired route to prepare novel organic–inorganic hybrids, which involves a diffusion-controlled deposition of inorganic minerals within porous polymeric matrices. Proper combination of controlled biomineralization technique with the rational choice of polymer templates would lead to the successful development of smart self-assembled drug carriers. The present work mainly summarizes our recent work about the biomineralized organic–inorganic hybrid materials aiming for smart drug delivery including hybrid beads, membranes, and micro/nano gels. Furthermore, prospect for future development of the smart organic–inorganic hybrids is also discussed.

Abstract:

Hybrid organic-inorganic catalysts have been extensively investigated by several research groups in the last decades, as they allow combining the structural robust-ness of inorganic solids with the versatility of organic chemistry. Within the field of hybrid catalysts, synthetic strategies based on silica are among the most exploitable, due to the convenience of sol-gel chemistry, to the array of silyl-derivative precursors that can be synthesized and to the number of post-synthetic functionalization strategies available, amongst others. This review proposes to highlight these advantages, firstly describing the most common synthetic tools and the chemistry behind sol-gel syntheses of hybrid catalysts, then presenting exemplificative studies involving mono- and multi-functional silica-based hybrid catalysts featuring different types of active sites (acid, base, redox). Materials obtained through different approaches are described and their properties, as well as their catalytic performances, are compared. The general scope of this review is to gather useful information for those approaching the synthesis of organic-inorganic hybrid materials, while providing an overview on the state-of-the art in the synthesis of such materials and highlighting their capacities.

Abstract:

In this PhD thesis, different types of hybrid organic-inorganic materials were studied as solid sorbents for the carbon dioxide capture, in order to give additional hints to the comprehension of phenomena playing an important role in CO2 adsorption processes. In the first part, hybrid organic-inorganic SBA-15 silicas functionalized with variable amount of amino groups were studied aiming to evaluate the influence of the different basic species on CO2 capture ability. Afterwards, it was decided to study the influence of siliceous support properties on the adsorption process. For this purpose, silica-based materials with different structure, morphology and particle size were selected and tested in the same experimental conditions, aiming to understand the effect of their physico-chemical properties on the CO2 adsorption. On one side MCM-41 silica-based materials with different particle diameter, passing from micrometric to nanometric scale, were considered, in order to study the size effect of the support on the adsorption properties. Furthermore, the effect of the porosity was evaluated by using as adsorbent a non-porous material (Stöber silica) and comparing the obtained results with those of MCM-41-based materials. Finally, the possible use of silica-based materials as catalyst for the carbon dioxide transformation into more useful products was studied. In particular, heterogeneous Cu-based catalyst supported on SiO2 have been studied as for the promotion of hydrogenation reaction of CO2 to formic acid.

Abstract:

The aim of this project was to prepare a series of silica materials based on sol-gel processing of alkoxysilanes using glucose and glycerol as templates for potential applications in membrane design for pervaporation. The materials were characterized using structural and dynamic techniques to gain information about the effect of the templates on the formation of micro- and mesoporous silicates. The interaction between templates and silica matrices were investigated using FTIR, Raman Spectroscopy, Solid State NMR Spectroscopy, Physisorption and SEM. Close contact between templates and silica networks was observed by NMR cross polarization studies. The chemistry was then extended to prepare hybrid organic-inorganic silica materials by introducing organic ligands, with glycerol as a template to control the porosity of the hybrid materials. By varying the ligand as well as the template, the physical properties of the gel can be controlled. Composites of hydroxypropylcellulose, HPC, and silica were also prepared and characterized. There was no phase separation during sol-gel processing suggesting HPC was dispersed homogenously in the silica matrices. This was also confirmed by solid state NMR. Temperature dependence showed some indications of conformational change in the HPC within the silicate, above 308K. The transport properties of the hybrid materials were observed by monitoring the diffusion behaviour of water and several selected solvents using Pulsed Field Gradient NMR. The self-diffusion of water and the organic solvents in the hybrid silica materials were two to three orders of magnitude smaller than in the liquid bulk suggesting restricted diffusion at the pore surface. The effect of surface polarity also contributed to water and solvents diffusivities. The temperature dependence of diffusion was useful to derive the activation energy whereas the dependence on NMR observation time provided information on both tortuosity and pore connectivity of the hybrid silica materials. The hybrid silica membranes were prepared by spin coating of polymeric silica sol on top of a macroporous alumina support after being occluded by colloidal silica. It was then used for pervaporation of water ethanol mixtures. The results implied that separation factor increased as the temperature increased. However permeate fluxes were less affected.

Abstract:

[ES] El trabajo de investigación descrito en la presente Tesis Doctoral ha sido desarrollado en el marco del proyecto europeo MULTI2HYCAT (grant agreement N. 720783) y se ha centrado en la síntesis y caracterización de materiales mono- y multi-funcionales que presentan sitios catalíticos ácidos, básicos o redox. Diferentes líneas de investigación han sido desarrolladas en paralelo para obtener distintos materiales híbridos que serán empleados en diferentes procesos catalíticos, en línea con las necesidades de los socios industriales del proyecto. Debido a la naturaleza colaborativa del proyecto, cada miembro académico se ha en-centrado en un aspecto del desarrollo de los materiales. Es por ello que el Instituto de Tecnología Química (ITQ-CSIC), donde se ha llevado a cabo esta Tesis Doctoral, se ha centrado en la síntesis de los catalizadores híbridos. Por ello, parte de la caracterización descrita en el Capítulo 3 se ha llevado a cabo en la Università del Piemonte Orientale (IT), durante una estancia de un mes. Ademas, algúnos resultados catalíticos descritos en los Capítulos 3 y 5 han sido obtenidos por la University of Southampton (UK). En el Capítulo 3, se ha descrito la síntesis de dos catalizadores heterogéneos híbridos que presentan moléculas de ácido aril-sulfónico en su composición. En uno de ellos, el anillo aromático presentará átomos de flúor en posición 2, 3, 5, 6. Se han llevado a cabo dos estrategias de síntesis multi-etapas, a través de la síntesis de los precursores alkoxi-silanos, a través de procesos de condensación junto a un precursor de sílice (en ausencia de agentes directores de estructura, a pH neutro y temperaturas bajas) y de una reacción de tethering. Los materiales híbridos han sido caracterizados a través de dife-rentes técnicas. Las propiedades texturales, la estabilidad térmica y la composición química de los catalizadores ha sido estudiada. Además, moléculas sondas han sido adsorbidas en los materiales hibridos y las interacciones entre ellos han sido estudiadas a través de espectroscopias FTIR y RMN multi-nuclear. El catalizador hibrido en que el anillo aromático estaba fluorado resultó ser el más activo catalíticamente en la reac-ción de formación de acetal entre benzaldehído y etilenglicol. Una versión de los hí-bridos en que la superficie había sido pasivada con grupos metilos también fue obteni-da. Las propiedades de los materiales híbridos pasivados fueron comparadas, para po-der estudiar el efecto de la polaridad de la superficie del soporte sobre la actividad catalítica. En el Capítulo 4 se describe la síntesis de órgano-catalizadores híbridos obtenidos por anclaje de precursores de silicio funcionalizados con grupos básicos sobre un soporte del tipo MCM-41. Los catalizadores han sido caracterizados y empleados en diferentes reacciones de formación de enlaces C-C, como la condensación de Knoevenagel y la adición de Michael. Los catalizadores híbridos han sido empleados en la condensación entre furfural y metil isobutil cetona. El catalizador más activo ha sido seleccionado para ser funcionalizado posteriormente con nanoparticulas de paladio y empleado en un proceso catalítico en cascada. Mecanismos de reacción han sido pro-puesto para cada proceso catalítico. El efecto beneficioso debido a la presencia de los grupos silanoles en la superficie del soporte también fue analizado. En el Capítulo 5, la síntesis de catalizadores híbridos multi-funcionales fue descrita. Basándose en los resultados obtenidos en el Capítulo 4, se ha preparado un catalizador que presente grupos aminopropil- y nanopartículas de paladio. Las propiedades estructurales y texturales han sido estudiadas. Además, a través de la microscopia electrónica de transmisión, la distribución dimensional de las nanoparticulas ha sido estimada, resultando en un tamaño medio equivalente a la dimensión de los canales mesoporosos del soporte, MCM-4
[CA] El treball de recerca descrit en aquesta tesi doctoral es va desenvolupar en el marc del projecte europeu MULTI2HYCAT (grant agreement N. 720783) i se centra en la sínte-si i la caracterització de catalitzadors híbrids mono i multifuncionals amb àcid, base o redox actius llocs. S'han desenvolupat diverses línies d'investigació en paral·lel per dissenyar múltiples catalitzadors híbrids per a diferents processos catalítics, basant-se en les necessitats dels socis industrials. A causa del caràcter col·laboratiu del projecte, cada soci acadèmic es va centrar princi-palment en un aspecte de tot el procés. Institut de Tecnologia Química (ITQ-CSIC), on es va desenvolupar aquesta tesi, està principalment centrat en el disseny i síntesi de catalitzadors híbrids. Per això, part dels resultats de caracterització reportats al Capítol 3 s'han dut a terme a la Università del Piemonte Orientale (IT), durant una estada d'un mes. Alguns dels resultats catalítics reportats al Capítol 3 i al Capítol 5 han estat reali-tzats per la Universitat de Southampton (Regne Unit). En el Capítol 3, s'ha descrit la síntesi de dos catalitzadors heterogenis híbrids que pre-senten molècules d'àcid aril-sulfònic en la composició. En un d'ells, l'anell aromàtic presentarà àtoms de fluor en posició 2, 3, 5, 6. S'han dut a terme dues estratègies de síntesi multi-etapes, a través de la síntesi dels precursors alkoxi-silans, mitjançant pro-cessos de condensació al costat d'un precursor de sílice (en absència d'agents directors d'estructura, a pH neutre i temperatures baixes) i d'una reacció de tethering. Els mate-rials híbrids han estat caracteritzats mitjançant diferents tècniques. Les propietats texturals, l'estabilitat tèrmica i la composició química dels catalitzadors ha sigut estudiada. A més, molècules sondes han estat adsorbides en els materials híbrids i les interaccions entre ells han estat estudiades mitjançant espectroscòpies FTIR i RMN multi-nuclear. El catalitzador híbrid en que l'anell aromàtic estava fluorat va resultar ser el més actiu catalíticament en la reacció de formació d'acetal entre benzaldehid i etilenglicol. Una versió dels híbrids en que la superfície havia estat pasivada amb grups metilos també va ser obtinguda. Les propietats dels materials híbrids passivats van ser comparades, per poder estudiar l'efecte de la polaritat de la superfície del suport sobre l'activitat catalítica. En el Capítol 4 es descriu la síntesi d'organo-catalitzadors híbrids obtinguts per ancoratge de precursors de silici funcionalitzats amb grups bàsics sobre un suport del tipus MCM-41. Els catalitzadors han estat caracteritzats i empleats en diferents reaccions de formació d'enllaços C-C, com la condensació de Knoevenagel i l'addició de Michael. Finalment, els catalitzadors híbrids han estat emprats en la condensació entre furfural i metil isobutil cetona. El catalitzador més actiu ha estat seleccionat per a ser funcionalitzat posteriorment amb nanoparticules de pal·ladi i emprat en un procés catalític en cascada. Mecanismes de reacció han estat proposat per a cada procés catalític. L'efecte beneficiós a causa de la presència dels grups silanols en la superfície de suport també va ser analitzat. En el Capítol 5, la síntesi de catalitzadors híbrids multi-funcionals va ser descrita. Basant-se en els resultats obtinguts en el Capítol 4, s'ha preparat un catalitzador que presenti grups aminopropil- i nanopartícules de palladi. Les propietats estructurals i texturals han estat estudiades. A més, a través de la microscòpia electrònica de trans-missió, la distribució dimensional de les nanoparticulas ha estat estimada, resultant en una grandària mitjana equivalent a la dimensió dels canals mesoporosos del suport, MCM-41. El material ha estat emprat com a catalitzador multi-funcional.
[EN] The research work described in this Doctoral Thesis was developed within the frame of the MULTI2HYCAT European Project (grant agreement N. 720783) and it is focused on the synthesis and characterization of mono- and multi-functional hybrid catalysts featuring acid, base or redox active sites. Several research lines have been developed in parallel to design multiple hybrid catalysts for different catalytic processes, building upon the needs of the industrial partners. Due to the collaborative nature of the project, each academic partners mainly focused on one aspect of the whole process. Instituto de Tecnología Química (ITQ-CSIC), where this Thesis was developed, mostly focused on the design and synthesis of the hybrid catalysts. For that, part of the characterization results reported in Chapter 3 have been carried out at Università del Piemonte Orientale (IT), during a one month stay. Some of the catalytic results reported in Chapter 3 and Chapter 5 have been car-ried out by the University of Southampton (UK). In Chapter 3 the synthesis of two different heterogeneous hybrid catalysts carrying aryl-sulfonic moieties, in which the aromatic ring was either fluorinated or not, is re-ported. Two multi-step synthetic approaches were developed, involving the synthesis of the silyl-derivative precursor, template-free one-pot co-condensation (at low tem-perature and neutral pH) and tethering reaction. A multi-technique approach was im-plemented to characterize the hybrid catalysts. Textural properties, thermal stability and chemical makeup of the materials were studied. Moreover, probe molecules were adsorbed onto the hybrids and the interaction were studied with multi-nuclear NMR and FTIR spectroscopies. The catalytic activity of the two hybrids showed superior performances for the fluoro-aryl-sulfonic acid, compared to the non-fluorinated mate-rial, in the acetal formation between benzaldehyde and ethylene glycol. Silanol-capped versions of the hybrids have also been prepared and their properties have been com-pared with those of hydrophilic hybrids, to study the effect of the polarity of the sur-face on the overall catalytic activity of the hybrids. In Chapter 4, the synthesis of hybrid mesoporous organocatalysts, obtained by graft-ing of commercial and custom-made silyl-derivatives onto MCM-41 supports, is re-ported. The hybrid catalysts were characterized and tested for different reactions in-volving C-C bond formation, such as Knoevenagel condensations and Michael addi-tion. Finally, the catalysts were tested in the condensation between furfural and methyl isobutyl ketone and the most performing catalyst was selected for the synthesis of a multi-functional hybrid. Reaction mechanisms have been proposed and the beneficial effect of the surface silanol groups on the catalytic activity was demonstrated. In Chapter 5, the synthesis of hybrid multi-functional catalysts is reported. Building upon the results reported in Chapter 4, a hybrid catalyst featuring aminopropyl moie-ties and palladium nanoparticles was developed. Structural and textural properties of the catalysts were accessed. Moreover, transmission electron microscopy showed a narrow nanoparticles distribution, centered a value equivalent to the size of the meso-porous channels of the support. The catalyst was tested in a tandem process involving the aldol condensation between furfural and methyl isobutyl ketone followed by hy-drogenation of the aldol adduct. The influence of several variables on the activity of the multi-functional catalyst was explored, with the scope of paving the way for more thorough studies to be carried out in flow regime. Lastly, proof-of-concept syntheses of multi-functional hybrid catalysts featuring base sites and supported metal complex are reported.

Abstract:

The separation of industrially important gases into pure supplies that can be used for many practical applications is based mainly on energy intensive methods such as the cryogenic distillation which is costly and energy intensive. Therefore other routes have been introduced to industrial separation of gases such as the selective adsorption using porous solid materials. Zeolites and activated carbon are the most widely used recyclable energy-efficient porous solid materials for industrial gas separations, however the low uptake and selectivity hurdles their commercialization in some separation applications. Metal organic frameworks (MOFs) have been extensively studied as solid porous materials in term of gas separations nevertheless the future of MOFs for practical gas separations is considered to be vague and stringent due to their low stability, low capacity and selectivity especially at low partial pressures of the adsorbed gas, the competitive adsorption of the contaminants such as H2O, NOX and SOX, high cost of the organic ligands, besides the challenges of the formulation of MOFs which is very important in the MOFs marketing. In this context we present new porous materials based on inorganic linkers as well as the organic molecules, Organic-Inorganic Hybrid Materials, which were found to conquer the current challenges for the exploitation of MOFs in practical gas separation such as separation of trace and low CO2 concentrations and Xe separation from Xe/Kr mixtures. The work presented herein encompasses the development of novel 48.67 topology metal organic material (MOM) platform of formula [M(bp)2(M'O4)] (M= Co or Ni; bpe= bipyridine-type linkers; M'= W, Mo or Cr) that have been assigned RCSR code mmo based upon pillaring of [M(bp)2] square grids by angular WO42-, MoO42- or CrO42- pillars. Such pillars are unexplored in MOMs. They represent ideal platforms to test the effect of pore size and chemistry upon gas sorption behavior since they are readily fine-tuned and can be varied at their 3-positions (metal, organic linker and the inorganic pillar) without changing the overall structure. Such an approach allows for systematic control of pore size to optimize interactions between the framework and the adsorbent in order to enhance selectivity and/or gas uptake. Interestingly, these nets showed a high chemical stability in air, water, boiling water and in a wide range of pH which is certainly a desirable property in industry and commercialization of MOMs. [Ni(bpe)2(MoO4)] (bpe= 1,2-bis(4-pyridyl) ethane), MOOFOUR-1-Ni, and its chromate analog, CROFOUR-1-Ni, exhibit remarkable CO2 affinity and selectivity, especially at low loading. This behavior can be attributed to exceptionally high isosteric heats of adsorption (Qst) of CO2 in MOOFOUR-1-Ni and CROFOUR-1-Ni of ~56 and ~50 kJ/mol, respectively, at zero loading. These results were validated by modeling which indicate that the electrostatics of such inorganic anions towards CO2 affords favourable attractions to CO2 that are comparable to the effect of unsaturated metal centres. The use of WO42- instead of CrO42- or MoO42- as an angular pillar in mmo topology nets has afforded two isostructural porous nets of formula [M(bpe)2WO4] (M = Co or Ni, bpe=1,2-(4-pyridyl)ethene). The Ni variant, WOFOUR-1-Ni, is highly selective towards CO2 thanks to its exceptionally high isosteric heat of adsorption (Qst) of -65.5 kJ/mol at zero loading. The fine-tunability and the inherent modularity of this platform allow us exquisite design and control over the pore chemistry through the incorporation of different functionalities inside the channels of the networks which was then demonstrated as valuable strategy in terms of carbon dioxide capture at condition relevant to the direct CO2 capture from air. The exploitation of 4,4'-azopyridine in the design and synthesis of CROFOUR-2-Ni, an isostructure of CROFOUR-1-Ni, affords a paradigm shift in the CO2 adsorption properties as exemplified by the enhanced CO2 isosteric heat of adsorption at moderate and high loading in CROFOUR-2-Ni and the superior CO2 selectivity even for trace and low CO2 concentration. The two isostructures, CROFOUR-1-Ni and CROFOUR-2-Ni have been also investigated in term of Xe adsorption and separation from Xe/Kr mixtures. The two structures were found to exhibit the remarkable Xe affinity and selectivity which, together with high stability, good recyclability, low regeneration energy and low cost of the two materials could not only diminish the cost of the Xe and Kr production but also can potentially afford a high purity of the separated gases.

Abstract:

Lors de leur stockage ou de leur exposition, les objets du patrimoine sont soumis à des processus physico-chimiques d’altération liés à leur environnement et en particulier à l’action de polluants primaires (e.g. dioxyde de soufre, oxydes d’azote), secondaires (ozone) ou de composés organiques volatils (COVs). Il a été démontré que ces gaz/vapeurs se comportent comme des agents d’hydrolyse et d’oxydation. L’acide acétique fait partie des COVs ayant un impact considérable et reconnu dans la conservation des objets du patrimoine en particulier des films photographiques. En vue de lutter contre ses effets délétères, ce projet de thèse s’est focalisé sur la conception de nouveaux matériaux poreux hybrides multifonctionnels appelés « Metal-Organic Frameworks » (MOFs) pour la capture sélective de l’acide acétique en présence d’humidité (40% humidité relative) et à température ambiante. Les remarquables propriétés d’adsorption (sensibilité, sélectivité et capacité) et la grande versatilité des MOFs (balance hydrophile/hydrophobe, taille/forme des pores,…) ont été utilisés pour préconcentrer de façon sélective l’acide acétique en milieu humide. Les matériaux les plus performants ont ensuite été préparés sous forme de nanoparticules pour l’élaboration de films minces de qualité optique afin d’en étudier les propriétés d’adsorption et de co-adsorption (acide acétique/eau) par ellipsométrie. L’incorporation de nanoparticules métalliques plasmoniques a ensuite été effectuée afin de concevoir un capteur colorimétrique. L’objectif final de ce travail est de concevoir un nouveau type d’adsorbant caractérisé par une capacité et une sélectivité d’adsorption élevée et dont on pourrait aisément déterminer le niveau de saturation en acide acétique afin d’anticiper son remplacement et ainsi assurer la préservation des objets stockés et exposés dans les musées
During their storage or their exhibition, the cultural heritage objects undergo physicochemical alteration processes related to their environment and in particular to the action of primary (e.g. sulfur dioxide, nitric oxides), secondary (ozone) pollutants or Volatile Organic Compounds (VOCs). It has been demonstrated that these gases/vapors are involved in hydrolysis and oxidation reactions. Among the most common VOCs encountered in museums, Acetic acid has a significant and recognized role in the deterioration of cultural heritage objects such as photographic films. In order to face this issue, this Ph.D. thesis focused on the design of new porous multifunctional hybrid materials denoted « Metal-Organic Frameworks » (MOFs) for the selective capture of acetic acid in the presence of moisture (40% relative humidity) and at room temperature. The remarkable adsorption properties (sensitivity, selectivity and capacity) and the great versatility of MOFs (hydrophicity/hydrophobicity balance, size/shape of pores,…) were used to preconcentrate selectively the acetic acid in humid conditions. The most performing materials were then prepared as nanoparticles and then used for the elaboration of high optical quality thin films in order to study the coadsorption (acetic acid/water) properties of MOFs by ellipsometry. The incorporation of plasmonic metal nanoparticles was then carried out in order to design a colorimetric sensor. The final objective is to devise a novel type of adsorbent that integrates a high VOC adsorption capacity and selectivity under humid conditions and an easy on-line monitoring of their saturation capacityin order to anticipate its replacement and therefore ensure the preservation of the stored and exhibited objects in museums

Abstract:

Nanotechnology as a field has the potential to answer some of the major challenges that mankind faces in regards to environmental sustainability, energy generation and health care. Though, solutions to these concerns can not necessarily rely on our current knowhow. Instead, it is reasonable to expect that humanity must adapt and learn to develop new materials and methods to overcome the adversities that we are facing. This master thesis has involved developing novel materials, serving as a small step in the continuous march towards a bright future where this is possible. More specifically, this work sought to combine mesoporous magnesium carbonate with various metal-organic frameworks to utilize the beneficial aspects from each of these constituents. The ambition was that these could be joined to render combined micro-/mesoporous core-shell structures, with high surface areas and many active sites whilst maintaining a good permeability. Numerous different synthesis routes were developed and explored in the pursuit of viable routes to design novel materials with potential future applications within for instance drug delivery, water harvesting from air and gas adsorption. Coreshell structures of the hydrophilic mesoporous magnesium carbonate covered with the hydrophobic zeolitic imidazole framework ZIF-8 was successfully synthesized for the first time, and practical studies demonstrated a dramatically enhanced water stability, which is perceived to have an impact on further research on these materials. ZIF-67 was also combined with mesoporous magnesium carbonate in a similar manner. Further, Mg-MOF-74 was grown directly from mesoporous magnesium carbonate, where the latter acted as a partially self-sacrificing template, with the aim of rendering a porous hierarchical structure with contributions from the micro- and mesoporous ranges. The outcomes of all these syntheses were characterized using several analyzing methods such as scanning electron microscopy, X-ray diffraction, energy dispersive spectroscopy and nitrogen sorption analysis.

Abstract:

Three types of poly(norbornane carbonate) or PNC oligomers were synthesized and characterized via spectroscopic methods and elemental analyses to validate their chemical structures. Using the results from proton nuclear magnetic resonance (1H NMR) experiments, the degree of polymerization and size of each PNC chain was estimated via end-group analysis. All three types of PNC structures were both thermally-labile and acidolytically-labile, allowing them to be used as sacrificial materials in both direct-write and thermally-processed template systems. Thermogravimetric analysis (TGA) data was used to determine the kinetic parameters for the thermolytic decomposition reactions and evolved-gas analysis via mass spectrometry (TGA-MS) was used to determine the mechanisms for thermolytic degradation. PNC oligomers were freely-mixed with hydrogen silsesquioxane (HSQ) to form solutions that were spin-coated to form templated films. Transmission electron microscopy (TEM) showed that the free-mixing of PNCs with HSQ resulted in the agglomeration of the porogen molecules during the spincoating step. This phase-segregation produced domain sizes much larger than those of the individual chains, and during decomposition large pores were produced. To combat the phase segregation, hydrosilylation reactions were used to covalently bond vinyl end-capped PNC chains to silane-functionalized siloxane and silsesquioxane molecules. These matrix-like materials served as compatibilizers in order to improve the phase-compatibility of the sacrificial polymers in HSQ films. NMR and GPC analyses showed that the solids recovered from the hydrosilylation reactions were binary mixtures of hybrid nanocomposite molecules and residual ungrafted PNC chains. TEM imaging showed that the domains in these nanocomposite films had bimodal size distributions due to the presence of two components in the mixtures. The hybrid molecules produced pores ranging in size from about 6-13 nm as a result of improvements in the phase-compatibility of the grafted oligomers. However, the residual ungrafted oligomers in the blends produced larger domains measuring 30-40 nm. It is believed that separation difficulties can be avoided if the vinyl termination reaction conditions can be adjusted to ensure 100% conversion of all the terminal hydroxyl groups to vinyl groups. Doing so would allow all PNC chains to be grafted during hydrosilylation reaction; thus, avoiding the recovery of free PNC oligomers.

Abstract:

The germylenes, germanium(II) 2-(oxidomethyl)phenolate (1), germanium(II) 4-methyl-2-(oxidomethyl)phenolate (2) and germanium(II) 4-bromo-2-(oxidomethyl)phenolate (3) were synthesized and their thermally induced twin polymerization to give organic–inorganic hybrid materials was studied. The compounds 1–3 form oligomers including dimers, trimers and tetramers as a result of intermolecular coordination of the benzylic oxygen atom to germanium. The structural motifs were studied by single crystal X-ray diffraction analysis and DFT-D calculations. Thermally induced twin polymerization of these germylenes gave hybrid materials based on germanium-containing phenolic resins. Carbonization of these resins under reductive conditions resulted in porous materials that are composed of germanium and carbon (Ge@C materials), while oxidation with air provided non-porous germanium dioxide. The porous Ge@C materials were tested as potential anode materials for rechargeable Li-ion batteries. Reversible capacities of 540 mA h g−1 were obtained at a current density of 346 mA g−1 without apparent fading for 100 cycles, which demonstrates that germanium is well accessible in the hybrid material

Abstract:

Objectives: 1) develop a thorough understanding of the sorption mechanisms of Pi and Po onto the Al/O- WTR; 2) determine the breakthrough range of the composite Al/O-WTR during P capturing from agro- wastewaters; and 3) critically evaluate the performance of the composite Al/O-WTR as a fertilizer using selected plants grown in lysimeters and test-field studies. Instead of lysimeters we used pots (Israel) and one- liter cone-tainers (USA). We conducted one field study but in spite of major pretreatments the soils still exhibited high enough P from previous experiments so no differences between control and P additions were noticeable. Due to time constrains the field study was discontinued. Background: Phosphorous, a non-renewable resource, has been applied extensively in fields to increase crop yield, yet consequently has increased the potential of waterway eutrophication. Our proposal impetus is the need to develop an innovative method of P capturing, recycling and reuse that will sustain agricultural productivity while concurrently reducing the level of P discharge from and to agricultural settings. Major Conclusions & Achievements: An innovative approach was developed for P removal from soil leachate, dairy wastewater (Israel), and swine effluents (USA) using Al-based water treatment residuals (Al- WTR) to create an organic-Al-WTR composite (Al/O-WTR), potentially capable of serving as a P fertilizer source. The Al-WTR removed 95% inorganic-P, 80% to 99.9% organic P, and over 60% dissolved organic carbon from the agro-industrial waste streams. Organic C accumulation on particles surfaces possibly enhanced weak P bonding and facilitated P desorption. Analysis by scanning electron microscope (SEM- EDS), indicated that P was sparsely sorbed on both calcic and Al (hydr)oxide surfaces. Sorption of P onto WW-Al/O-WTR was reversible due to weak Ca-P and Al-P bonds induced by the slight alkaline nature and in the presence of organic moieties. Synchrotron-based microfocused X-ray fluorescence (micro-XRF) spectrometry, bulk P K-edge X-ray absorption near edge structure spectroscopy (XANES), and P K-edge micro-XANES spectroscopy indicated that adsorption was the primary P retention mechanism in the Al- WTR materials. However, distinct apatite- or octocalciumphosphatelike P grains were also observed. Synchrotron micro-XRF mapping further suggested that exposure of the aggregate exteriors to wastewater caused P to diffuse into the porous Al-WTR aggregates. Organic P species were not explicitly identified via P K-edge XANES despite high organic matter content, suggesting that organic P may have been predominantly associated with mineral surfaces. In screen houses experiments (Israel) we showed that the highest additions of Al/O-WTR (5 and 7 g kg⁻¹) produced the highest lettuce (Lactuca sativa L. var. longifolial) yield. Lettuce yield and P concentration were similar across treatments, indicating that Al/O- WTR can provide sufficient P to perform similarly to common fertilizers. A greenhouse study (USA) was utilized to compare increasing rates of swine wastewater derived Al/O-WTR and inorganic P fertilizer (both applied at 33.6, 67.3, and 134.5 kg P₂O₅ ha⁻¹) to supply plant-available P to spring wheat (TriticumaestivumL.) in either sandy loam or sandy clay loam soil. Spring wheat straw and grain P uptake were comparable across all treatments in the sandy loam, while Al/O-WTR application to the sandy clay loam reduced straw and grain P uptake. The Al/O-WTR did not affect soil organic P concentrations, but did increase phosphatase activity in both soils; this suggests that Al/O-WTR application stimulated microorganisms and enhance the extent to which microbial communities can mineralize Al/O-WTR-bound organic P. Implications: Overall, results suggest that creating a new P fertilizer from Al-WTR and agro-industrial waste sources may be a feasible alternative to mining inorganic P fertilizer sources, while protecting the environment from unnecessary waste disposal.
