Résumé :

Binary organic-inorganic mesoporous hybrid materials were prepared by covalntly grafting Lanthanide (III) (Eu) trifluoroacetylaceton (TAA) complexes to the ordered meosoporous silica SBA-15 via hydrothermal method and hydrolysis and co-polycondensation method with the surfactant P123 and TEOS. Besides, Novel ternary lanthanide (III) (Eu) organic-inorganic-polymeric mesoporous hybrid materials have been synthesized as well through the introduction of the organic polymer PMAA to the binary system with covalent bond. We investigated the thermal stability and luminescence properties of hybrids and found that the ternary hybrid materials exhibit better thermal stability and stronger emission intensity. Furthermore, compared with the binary mesoporous material Eu (TAA-SBA-15)3, the ternary mesoporous material Eu (TAA-SBA-15)3PMMA exhibits the characteristic emission of the Eu3+ ion with a higher luminescence Intensity, suggesting that the introduction of polymer PMMA into the mesoporous matrix is of benefit for the sensitization of Eu3+ luminescence, by replacing H2O groups that can quench the luminescence of Eu3+ ion.

Résumé :

Organic-inorganic hybrid monoliths with well-defined macropores and/or mesopores have been synthesized by a sol-gel process accompanied by polymerization-induced phase separation. Using aklyltrialkoxysilanes and alkylene-bridged alkoxysilanes, two different categories of organo-siloxane networks have been characterized in view of macroporoisity based on phase separation as well as mesoporosity based on supramolecular templating by surfactants. The alkyl-terminated polysiloxane network exhibited substantial surface hydrophobicity together with the mechanical flexibility. On the other hand, the alkylene-bridged network behaved much more similarly to those prepared from tetraalkoxysilanes with regard to surface hydrophilicity, mechanical rigidness and mesopore-forming ability. Supramolecular templating of mesopores embedded in the gel skeletons comprising well-defined macroporous network has proven to give wide variety of hierarchically designed macro-mesoporous organic-inorganic hybrid materials.

Résumé :

Catalyst selectivity is associated with well-defined homogeneous active sites. Transition metal complexes and organocatalysts are highly active and selective in the homogeneous phase, and their heterogenization by incorporating them into inorganic solid materials allows combining their excellent catalytic activity with improved separation, recovering and recycling properties. In this article, we present the structural characteristics and catalytic properties of hybrid organic–inorganic materials in which the molecular catalysts are part of the inorganic structure, emphasizing the possibilities of periodic mesoporous hybrid materials and coordination polymers as single-site solid catalysts.

Résumé :

For the first time, mesoporous nickel–titanium-trimesic acid (NTT) inorganic–organic hybrid composite was synthesized in water-in-[Bmim]PF6 ionic liquid microemulsions using the trimesic acid (BTC) as the linker. The synthesized NTT was characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) analysis, powder X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FT-IR) methods, etc. Then, the isotherm and kinetic of adsorption were studied. The experimental data were well fitted with isotherm models of Langmuir and Freundlich (IMLF) at 298 K and 308 K and better fitted with the isotherm model of Langmuir (IML) at 318 K with the adsorption capacity of 662.212 μmol/g (maximum). The adsorption of rhodamine B (RhB) on NTT can be described by pseudo-second-order (PSO) kinetic model. This proposed method for synthesis of mesoporous NTT inorganic–organic hybrid composite is facile, environment-friendly and operated at room temperature, which could be applied to synthesis of other mesoporous inorganic–organic hybrid composites.

Résumé :

This work reports the covalent attachment of three different calix[4]arenes (calix[4]arene (C4), p-sulfonatocalix[4]arene (C4S), and p-tert-butyl-calix[4]arene (PC4)) to MCM-41, using a three-step modification process. 3-Chloropropyltrimethoxysilane (ClPTS) was first attached to the mesoporous silica surface and subsequently converted to amides via the reaction with toluene diisocyanate (TDI). Finally, calix[4]arene derivatives attached to the isocyanate ending remained available on toluene di-iso-cyanate. Changes in the surface properties of the mesoporous silica caused by the chemical modification were monitored using the Fourier transform infrared spectroscopy (FTIR), thermal analysis (TGA), and elemental analysis. The FTIR spectra and TGA analysis verify that the calix[4]arene derivatives are covalently attached to the mesoporous silica. The preservation of the MCM-41 channel system was checked by the X-ray diffraction and nitrogen adsorption analysis. These materials were then used to evaluate the sorption properties of some organotins compounds (Tributyltin (TBT), Triphenyltin (TPT), and Dibutyltin (DBT)).

Résumé :

The organic ligand sulfosalicylic acid (SSA) which was selected as molecular bridge for sensitization of terbium ions was modified by thionyl chloride (SOCl2) and 3-ammonium propyl triethoxy silane (APTES) to obtain the hybrid precursor SSA-Si. Then the solution of Tb (NO3)3was added in the presence of tetraethylorthosilicate (TEOS). The binary lanthanide organic/inorganic hybrid material was obtained. The ternary hybrid material was obtained by adding the solution of Tb (NO3)3and polyurethane. We investigated the thermal stability and luminescence properties of hybrids and found that the ternary hybrid materials exhibit better thermal stability and stronger emission intensity. Furthermore, compared with the binary mesoporous material Tb-(SSA-Si)3, the ternary mesoporous material Tb-(SSA-Si)3-PU exhibits the characteristic emission of the Tb3+ion with a higher luminescence intensity, suggesting that the introduction of polymer polyurethane into the mesoporous matrix is of benefit for the sensitization of Tb3+luminescence, by replacing H2O groups that can quench the luminescence of Tb3+ion.

Résumé :

Hybrid inorganic–organic materials are promising systems for a variety of applications due to their extraordinary properties with intricate composite architectures composed of nanoscale inorganic moieties with organic polymers synergistically intertwined to provide both useful functionality and mechanical integrity. These materials have a high potential for future applications and therefore attract considerable interest in polymer science research during the last years. Among the various explored inorganic nanostructures, the mesoporous silica has been considered as a fascinating material to construct novel ordered and well-dispersed nanocomposites due to their high surface areas, periodic and size-controllable pore channels. This review is written with the intention to give an overview of the characterization and material properties of polymer–mesoporous silica nanocomposites. Among polymer–mesoporous silica composites, various categories including polyaniline, polypyrrole, polystyrene, polypropylene, polyethylene, epoxy, rubber, and acrylate polymer were discussed in detail.

Résumé :

A hierarchical meso-/macroporous titanium phosphonate (TPPH) hybrid material was prepared via a simple surfactant-assisted process with the use of the precursor tetrabutyl titanate and 1-hydroxy ethylidene-1,1-diphosphonic acid. The prepared hybrid TPPH presented amorphous phase, exhibiting a hierarchical macroporous structure composed of mesopores with a pore size of 2.0 nm. The BET surface area is 256 m2/g. The hydroxyethylidene-bridged organophosphonate groups were homogeneously incorporated in the network of the hierarchical porous solid, as revealed by FT-IR, MAS NMR, XPS, and TGA measurements. The optical properties and photocatalytic activity of the hierarchical TPPH material were investigated in comparison with those of hierarchical porous titanium phosphate and pure mesoporous titania materials, showing superiority of the inorganic-organic hybrid framework, suggesting promising photocatalysts for wastewater cleanup.

Résumé :

AbstractThe paper concerns application of two types of organic materials – porous aromatic frameworks (PAFs) with diamond-like structure and the ordered mesoporous phenol-formaldehyde polymers (MPFs) – as supports for metal and metal sulfide nanoparticles. The obtained hybrid materials were tested in hydrogenation of various unsaturated and aromatic compounds. Ruthenium catalyst, based on PAF (Ru-PAF-30), possessed high activity in exhaustive hydrogenation of phenol into cyclohexanol with TOF value of 2700 h−1. Platinum catalyst, based on modified with sulfo-groups MPF (MPF-SO3H-Pt), was selective in semi-hydrogenation of terpenes, [α-terpinene, γ-terpinene, terpinolene, (s)-limonene]. Bimetallic Ni–W sulfide catalysts, prepared by in situ decomposition of [(n-Bu)4N]2Ni(WS4)2 within the pores of MPFs and PAFs, possessed high efficiency in hydrogenation-hydrocracking of naphthalenes as model substrates.

Résumé :

Our research group has developed a group of hybrid biomedical materials potentially useful in the healing of diabetic foot ulcerations. The organic part of this type of hybrid materials consists of nanometric deposits, proceeding from the Mexican medicinal plantTournefortia hirsutissimaL., while the inorganic part is composed of a zeolite mixture that includes LTA, ZSM-5, clinoptilolite, and montmorillonite (PZX) as well as a composite material, made of CaCO3and montmorillonite (NABE). The organic part has been analyzed by GC-MS to detect the most abundant components present therein. In turn, the inorganic supports were characterized by XRD, SEM, and High Resolution Adsorption (HRADS) of N2at 76 K. Through this latter methodology, the external surface area of the hybrid materials was evaluated; besides, the most representative textural properties of each substrate such as total pore volume, pore size distribution, and, in some cases, the volume of micropores were calculated. The formation and stabilization of nanodeposits on the inorganic segments of the hybrid supports led to a partial blockage of the microporosity of the LTA and ZSM5 zeolites; this same effect occurred with the NABE and PZX substrates.

Résumé :

Sol–gel synthesis is used for the fabrication of new materials with technological applications including ceramics for implants manufacturing, usually termed bioceramics. Many bioactive and resorbable bioceramics, that is, calcium phosphates, glasses and glass–ceramics, have been improved by using the sol–gel synthesis. In addition, the soft thermal conditions of sol–gel methods made possible to synthesize more reactive materials than those synthesized by traditional methods. Moreover, new families of bioactive materials such as organic–inorganic hybrids and inorganic compounds with ordered mesostructure can be produced. In hybrid materials, the inorganic component ensures the bioactive response whereas the organic polymeric component allows modulating other properties of the resulting biomaterial such as mechanical properties, degradation, etc. On the other hand, the sol–gel processes also allow the synthesis of silica ordered mesoporous materials, which are bioactive and exhibit – as an added value – a possible application as matrices for the controlled release of biologically active molecules (drugs, peptides, hormones, etc.). Finally, by combining the bioactive glasses composition with synthesis strategies of mesoporous materials, template glasses with ordered mesoporosity can be obtained. In this chapter, the advances that sol–gel technology has brought to the silica-based bioactive bioceramics are presented.

The organic ligand 2-Thenoyltrifluoroacetone (TTA) which was selected as molecular bridge for sensitization of europium and terbium ions were modified by 3-(triethoxysilyl)-propylisocyanate (TEPIC) to obtain the hybrid precursor TTA-Si. Then the solution of Eu(NO3)3 and Tb(NO3)3 were added in the presence of tetraethylorthosilicate (TEOS). The binary lanthanide organic/inorganic hybrid material were obtained. The ternary hybrid materials were obtained by adding the solution of Eu(NO3)3 and Tb(NO3)3 and Poly (ethylene glycol) (PEG400). We investigated the thermal stability and luminescence properties of hybrids and found that the ternary hybrid materials exhibit better thermal stability and stronger emission intensity. Furthermore, compared with the binary mesoporous material Eu-(TTA-Si)3 and Tb-(TTA-Si)3, the ternary mesoporous material Eu-(TTA-Si)3-PEG and Tb-(TTA-Si)3-PEG exhibits the characteristic emission of the Eu3+ and Tb3+ ion with a higher luminescence intensity, suggesting that the introduction of PEG is of benefit for the sensitization of Eu3+ and Tb3+ luminescence, by replacing H2O groups that can quench the luminescence of Eu3+ and Tb3+ ions.

Résumé :

It is widely recognized that the presence of defects in crystals and other solid materials can have a profound effect upon their chemical and physical properties and, consequently, that defects have a major impact on the practical utility of many technological materials. The presence of defects in a crystalline material implies the presence of disorder, and the extent of such disorder can range from very minor, such as the occurrence of Schottky defects in a crystal of sodium chloride, to maximum disorder, as in an amorphous material. The focus of this overview is on systems that are partially disordered, spanning the range between—but not including—sodium chloride and an amorphous material. Even within this range, the aim is not to be comprehensive, since for space reasons we have restricted our coverage to inorganic materials and hybrid inorganic-organic systems. The choice of this topic stems from both its fundamental and practical importance; it is also a very timely topic. For example, there is a great deal of current interest in complex, partially ordered materials such as the surfactant-mediated mesoporous silicas, biominerals, and hybrid organic-inorganic composites. Research on such materials has presented challenges that cannot easily be addressed by characterization tools that have been developed for well-ordered materials. The same situation is found in other areas such as carbons (including nanotubes) and glassy metal oxides.

Résumé :

Solar hydrogen production via the photoelectrochemical water-splitting reaction is attractive as one of the environmental-friendly approaches for producing H2. Since the reaction simultaneously generates H2 and O2, this method requires immediate H2 recovery from the syngas including O2 under high-humidity conditions around 50 °C. In this study, a supported mesoporous γ-Al2O3 membrane was modified with allyl-hydrido-polycarbosilane as a preceramic polymer and subsequently heat-treated in Ar to deliver a ternary SiCH organic–inorganic hybrid/γ-Al2O3 composite membrane. Relations between the polymer/hybrid conversion temperature, hydrophobicity, and H2 affinity of the polymer-derived SiCH hybrids were studied to functionalize the composite membranes as H2-selective under saturated water vapor partial pressure at 50 °C. As a result, the composite membranes synthesized at temperatures as low as 300–500 °C showed a H2 permeance of 1.0–4.3 × 10−7 mol m−2 s−1 Pa−1 with a H2/N2 selectivity of 6.0–11.3 under a mixed H2-N2 (2:1) feed gas flow. Further modification by the 120 °C-melt impregnation of low molecular weight polycarbosilane successfully improved the H2-permselectivity of the 500 °C-synthesized composite membrane by maintaining the H2 permeance combined with improved H2/N2 selectivity as 3.5 × 10−7 mol m−2 s−1 Pa−1 with 36. These results revealed a great potential of the polymer-derived SiCH hybrids as novel hydrophobic membranes for purification of solar hydrogen.

Résumé :

Rare earth complex Eu(phen)2Cl3·2H2O synthesized by precipitation method was incorporated into MCM-41 mesoporous molecular sieves which were synthesized via a hydrothermal method. Hybrid inorganic/organic mesoporous luminescent material Eu(phen)2/MCM-41 has been characterized by XRD, TEM, IR, UV-visible spectra and fluorescence spectra. Results indicated that the hybrid mesoporous material has typical structure of MCM-41 and retains the same pore structure as MCM-41 after the assembly process. The fluorescence spectra of these materials present a series of narrow lines assigned to 5D0 → 7F0,1,2,3,4 transitions. The high emission intensity observed is a promising property for application of the rare earth complex in technological luminescent devices.
