Streszczenie:

The effect of support nature, SiO2 and γ-Al2O3, on physicochemical and catalytic properties of nickel phosphide catalysts in methyl palmitate hydrodeoxygenation (HDO) has been considered. Firstly, alumina-supported nickel phosphide catalysts prepared by temperature-programmed reduction method starting from different precursors (phosphate–Ni(NO3)2 and (NH4)2HPO4 or phosphite–Ni(OH)2 and H3PO3) were compared using elemental analysis, N2 physisorption, H2-TPR, XRD, TEM, NH3-TPD, 27Al and 31P MAS NMR techniques and catalytic experiments. The mixture of nickel phosphide phases was produced from phosphate precursor on alumina while using of phosphite precursor provides Ni2P formation with the higher activity in methyl palmitate HDO. Besides, the comparative study of the performances of Ni2P/SiO2 and Ni2P/Al2O3 catalysts demonstrates the apparent superiority of alumina-supported Ni2P in the methyl palmitate hydrodeoxygenation. Considering the tentative scheme of methyl palmitate transformation, we proposed that cooperation of Ni2P and acid sites on the surface of alumina provides the enhanced activity of alumina-supported Ni2P through the acceleration of acid-catalysed hydrolysis.

Streszczenie:

Nickel and nickel phosphide nanoparticles are highly useful in various fields, owing to their catalytic and magnetic properties. Although several synthetic protocols to produce nickel and nickel phosphide nanoparticles have been previously proposed, controllable synthesis of nanoparticles using these methods is challenging. Herein, we synthesized highly monodisperse nickel and nickel phosphide nanoparticles via thermal decomposition of nickel–oleylamine–phosphine complexes in organic solvents. The size and composition of the nickel and nickel phosphide nanoparticles were easily controlled by changing the aging temperature, precursor concentration, and phosphine surfactant type. Large-sized monodisperse nickel nanoparticles obtained using our method were successfully applied for the purification of histidine-tagged proteins.

Streszczenie:

The regioselectivity of hydrocyanation of a range of alkynols using nickel-based catalyst systems involving either triphenyl phosphite or α,α′-bis(diphenylphosphino)-o-xylene (phmep) has been investigated. The regioselectivity of the hydrocyanations involving the phosphine catalyst reflected dominant steric effects whereas results from the phosphite catalyst system showed some evidence for chelation control. Yields of nitriles from reactions based on the phosphite system were variable, whereas moderate to good yields of distilled products could be obtained consistently by using the phosphine -based system. An explanation for this variation in yield is proposed.

Streszczenie:

To activate the surface of cotton fabrics before chemical nickel plating, it is proposed to use physical and chemical processes occurring in thin layers of solutions of copper (II) chloride under the influence of electromagnetic solar rays of the visible spectrum. It is shown that cellulose, which is the main component of the fabric, undergoes photo-oxidation in the presence of copper (II) chloride. As a result of this interaction, well-bonded copper monochloride is formed. When further processing of the fabric with phosphine gas, copper monochloride is transformed into copper and copper phosphide. Copper phosphide is a catalyst for the chemical nickel plating process. This makes it possible to obtain an electrically conductive nickel-phosphorus coating on the surface of the fabric in conventional electrolytes of chemical nickel plating. It is also found that when screening individual sections, the processes leading to the formation of copper monochloride do not occur. This allows selective metallization of the fabric.

In this study, we present an investigation into various nickel phosphite and phosphite–phosphine complexes for use in the Mizoroki–Heck and Suzuki–Miyaura cross-coupling reactions and the ammonia arylation reaction. In these coupling reactions, it was discovered that the Ni[P(OEt)3]4, (dppf)Ni[P(OPh)3]2, and (binap)Ni[P(OPh)3]2 catalysts were the most effective. In addition, an optimisation process for these catalytic systems as well as functional group compatibility are discussed.

Streszczenie:

Dans ce manuscrit est exposée en premier lieu une méthode originale pour la synthèse de nanoparticules de phosphures de métaux (Ni2P, InP, FeP, Zn3P2). Le phosphore blanc (P4) est utilisé comme réactif stœchiométrique, en solution et dans des conditions douces (25-220°C), sur des précurseurs de métaux(0) (complexes organométalliques ou nanoparticules). Ce contrôle inédit de la stœchiométrie permet par la suite l’obtention de nanoparticules cœur-coquille Ni2P-Ni via un mécanisme de ségrégation de phase intraparticulaire, induit par la taille nanométrique des nanoparticules de nickel utilisées comme précurseur. Dans un second temps, les nanoparticules de phosphures de métaux sont évaluées en tant qu’électrodes négatives pour les batteries au lithium. Une calcination des nanoparticules sous atmosphère réductrice s’avère indispensable pour permettre la réaction du lithium avec l’électrode. Enfin, les propriétés de Ni2P en catalyse sont explorées. L’hydrogénation chemosélective des alcynes est réalisée en solution à une température basse (85°C) et compatible avec la présence de divers groupes fonctionnels sur l’alcyne
In this manuscript, an original synthesis of metal phosphide nanoparticles (Ni2P, InP, FeP, Zn3P2) is described first. White phosphorus (P4) was stoichiometrically reacted on metal(0) precursors (organometallic complexes or nanoparticles) in solution and under soft conditions (25-220°C). This unprecedented control of the stoichiometry also allowed the preparation of Ni2P-Ni core-shell nanoparticles, from nickel(0) nanoparticles, via a nanoscaled-induced phase segregation that occurs in each nanoparticle. Secondly, metal phosphide nanoparticles were evaluated as negative electrode for lithium batteries. Calcination of the nanoparticles under inert atmosphere was found to be critical for the electrochemical reaction of lithium with the electrode. Lastly, catalytic properties of Ni2P nanoparticles were investigated. The chemoselective hydrogenation of alkynes was achieved in solution at a low temperature (85°C), compatible with the presence of various functional groups on the alkyne

Streszczenie:

Les champignons mycorhiziens à arbuscules (AMF) sont des symbiotes nécessaires au développement d’environ 80% des plantes vasculaires (Brundrett 2009). Leur impact sur l’adaptation et la croissance des plantes est essentiel, en particulier dans les milieux pauvres comme les maquis miniers de Nouvelle-Calédonie. Les études réalisées jusqu’à présent en Nouvelle-Calédonie sur ce sujet ont démontré l’importance de ces symbiotes dans les maquis miniers et leur rôle dans la nutrition des plantes endémiques et plus généralement dans l’adaptation aux contraintes multiples de ces milieux (Amir et al. 1997 ; Perrier et al. 2006 ;Amir et al. 2007 ; Amir et al. 2008 ; Lagrange 2009 ; Amir et Ducousso 2010). La maîtrise de la symbiose plante/AMF dans ces écosystèmes est essentielle à la mise au point de méthodes de restauration écologique des terrains miniers dégradés, d’autant que les AMF sont des symbiotes non spécifiques et que le même champignon peut être utilisé pour mycorhizer de nombreuses espèces végétales. Toutefois nos connaissances actuelles restent insuffisantes, notamment en ce qui concerne la biodiversité de ces AMF et les mécanismes de leurs effets positifs sur la plante
In New Caledonia (NC), restoration of open-cat mining sites is far from being mastered. It still needs work, to be improved, especially in plants - soil - microorganisms relationships. These works have focus on description of arbuscular mycorrhizal fungi (AMF) diversity and role in the adaptation of plants to ultramafic constraint, with plant growth promoting rhibzobacteria (PGPR). The diversity of AMF is analyzed on two plant genera with species on ultramafic soils, nickel hyperaccumulat ing or not, and on volcano-sedimentary soils. The analysis of this diversity shows that community composition is contrasted between the two types of soil. Some of AMF taxa seem to be specific to ultramafic soils and some even to be specific to nickel hyperaccumulator species. For the role in adaptation of plants to ultramafic constraints, greenhouse experiments on three endemic species (Alphitonia meocaledonica, Carpolepis laurifolia and Costularia comosa) have shown that naturally brings mycorrhiza improved growth, mineral nutrition, water and Ca /Mg ration. Phosphorus additions seem to change these effects with different consequences on growth according to the host plant. Finally, the use of PGPR alone or with AMF showed that the effect depends on host plant species and bacterial strain, but usually leads to improved growth and plant nutrition. These studies have shown the importance of AMF in ultramafic soils NC

Ce manuscrit présente une synthèse originale de nanoparticules de nickel(0). L'utilisation d'un précurseur de dioléylamide de nickel(II) conduit à un procédé versatile, robuste, et sans eau pour la production de particules ajustables en taille entre 4 et 11 nm de diamètre. Cette méthode a été étendue pour former de petites nanoparticules de fer(0) et de cobalt(0). Ces particules ont été examinées en ce qui concerne l'activité catalytique, y compris l'hydrosilylation d'un alcène terminal, l'hydrogénation sélective du phénylacétylène en styrène, et la réduction sous-stoechiométrique de l'azote en tris(triméthylsilyl)amine. Le phosphore blanc (P4) a été réagi stoechiométriquement avec les nanoparticules métalliques pour former les nanoparticules de phosphure métallique correspondantes. Le phosphore blanc a été alternativement fonctionnalisé en utilisant un superhydrure (LiBEt3H) pour former une espèce phosphanide stabilisée au borane, LiPH2(BEt3)2. Cette espèce a été utilisée pour synthétiser diverses phosphines, y compris la phosphine, la tris(triméthylsilyl)phosphine, et les triaroylphosphines. Les adduits labiles de triéthylborane ont été remplacés par BH3, ce qui a donné lieu à la formation de LiPH2(BH3)2, qui peut avoir des applications dans la formation de polymères P-B
This manuscript presents an original synthesis of nickel(0) nanoparticles. The use of a nickel(II) dioleylamide precursor results in a versatile, robust, water-free method for the production of size-tunable particles between 4 - 11 nm in diameter. This method was extended to form small iron(0) and cobalt(0) nanoparticles. These particles were examined for catalytic activity, including the hydrosilylation of a terminal alkene, the selective hydrogenation of phenylacetylene to styrene, and the substoichiometric reduction of nitrogen to tris(trimethylsilyl)amine. White phosphorus (P4) was stoichiometrically reacted with the metal(0) nanoparticles to form the corresponding metal phosphide nanoparticles. White phosphorus was alternatively functionalized using superhydride (LiBEt3H) to form a borane-stabilized phosphanide species, LiPH2(BEt3)2. This species was used to synthesize various phosphines, including phosphine, tris(trimethylsilyl)phosphine, and triaroylphosphines. The labile triethylborane adducts were replaced by BH3, resulting in the formation of LiPH2(BH3)2, which may have applications in the formation of P-B polymers

Les conditions de syntheses electrochimiques d'alliages nickel-phosphore et fer-chrome-nickel, ont ete etudiees dans le but de diversifier les applications d'un nouveau materiau composite constitue de spheres creuses obtenues par electroformage. La technique d'elaboration par courant pulse permet de maitriser les mecanismes reactionnels de codeposition des alliages nickel-phosphore. Les conditions de cinetique et de thermodynamiques electrochimiques induites par les systemes d'impulsions conduisent a l'obtention d'alliages metal-metalloide de composition chimique et de morphologie controlees. La microstructure et les proprietes mecaniques dependent essentiellement de la composition chimique. L'enthalpie de cristallisation et la contraction liee au passage d'une structure amorphe a une structure cristallisee, sont en outre, fonctions lineaires de la teneur en phosphore. Les alliages fer-chrome-nickel ont ete elabores par une methode originale de codeposition/diffusion. La codeposition de particules de chrome dans une matrice fer-nickel n'est optimale que pour certaines combinaisons parametriques de courant pulse. La presence de particules modifie considerablement la morphologie des depots puisqu'elle inhibe la croissance colonnaire. Celle-ci s'effectue par contre a partir des particules conductrices codeposees en donnant naissance a une interface entre particule et matrice. Un traitement thermique de diffusion permet l'homogeneisation chimique de ces alliages. Suivant leur composition chimique, ces alliages presentent des resistances a la rupture 3 a 10 fois superieures a celles du nickel. De plus, la resistance a l'oxydation a haute temperature de l'alliage fe78,5 cr18,0 ni3,5 est equivalente a celle des aciers inoxydables. Les essais preliminaires de transposition a l'electroformage de spheres creuses ont permis d'aboutir a l'optimisation des proprietes mecaniques du materiau. Le remplacement du nickel par des alliages fer-chrome-nickel a ainsi conduit a doubler, apres recuit, la resistance mecanique a la compression des spheres

Le but de ce travail est d'etudier l'extension de coordination autour de l'atome de phosphore par chelation intramoleculaire n-p. L'extension de coordination a ete mise en evidence par etude rmn dynamique de differents phosphonates et phosphonites. Ceci nous a ensuite conduit a l'etude de phosphines hypercoordonnees et de leurs proprietes. Leur complexation avec les metaux carbonyles a montre que ces phosphines se comportent, selon les conditions experimentales, soit comme des ligands monodentes, soit comme des ligands bidentes. Dans les deux cas, les frequences ir des carbonyles sont fortement augmentees, ce qui montre la richesse en electrons de ces phosphines. Enfin, nous montrons que ces phosphines peuvent avoir des applications en synthese organique. Elles donnent des complexes du nickel et du palladium qui catalysent le couplage entre un derive organomagnesien et un halogenure vinylique. On obtient des melanges d'olefines plus riches en olefine z qu'avec les complexes classiques et dans certains cas, seule l'olefine z est obtenue.

Dans ces travaux de thèse, nous avons exploré différentes classes de nanoparticules métalliques telles que des carbures, des oxydes et des phosphures, pour des applications en catalyse colloïdale. Afin de construire un système catalytique de type « Paire de Lewis Frustrée », la synergie avec des bases de Lewis moléculaires a été étudiée. En introduction, les enjeux et les défis de l’activation de H2 en solvant sont présentés, avec un focus sur les catalyseurs non purement métalliques pour l’hydrogénation de composés modèles. Dans la première partie, des carbures et des hydrures de métaux de début de transition ont été synthétisés par métathèse solide-solide. Nous avons exploré l’influence de différents paramètres de procédé sur la spéciation de phase des produits. Les catalyseurs supportés les plus prometteurs, Mo2C/C et W2C/C, ont été étudiées pour l’hydrogénation d’oléfines en phase gaz et en solvant. Dans la deuxième partie, des oxydes de cerium et d’indium ont été produits par voie hydrothermale. L’importance de défauts d’oxygène dans CeO2-x pour l’activation de H2 en phase gaz et pour la semi-hydrogénation du phénylacétylène a été établie. La dernière partie est dédiée à la synthèse solvothermale d’oxydes de molybdène et de tungstène, ainsi qu’à celle de carbure et de phosphures de nickel. Les mécanismes de synthèse ont été étudiés par RMN pour la partie organique et par XAS et DRX pour la partie inorganique. L’activité catalytique des nanoparticules non supportées a finalement été évaluée pour l’hydrogénation du nitrobenzène et du phénylacétylène dans plusieurs solvants
In this thesis work, the use of metal-containing nanoparticles such as carbides, oxides and phosphides is explored for colloidal catalysis. In an attempt to build a Frustrated Lewis Pair (FLP)-like catalytic system for H2 activation, the synergy with a molecular Lewis base is assessed. In the bibliographic introduction, the stakes and the challenges of H2 activation in solvent are presented, with an emphasis on the use of non-purely metallic catalysts for the hydrogenation of model compounds. In the first part, early transition metal carbides and hydrides are synthesized via solid-state metathesis. The influence of process parameters is explored to tune the phase speciation in the products. The most promising carbon-supported catalysts, Mo2C/C and W2C/C, are studied for gas phase and liquid phase hydrogenations of olefins. In the second part, cerium and indium oxides are obtained via hydrothermal pathways. The relevance of oxygen defects in CeO2-x is established for H2 gas phase activation and semi-hydrogenation of phenylacetylene in solvent. The last part is dedicated to the non-aqueous syntheses of molybdenum and tungsten oxides, and nickel carbide and phosphides. The syntheses mechanisms are studied by means of NMR for the organic species and XAS and XRD for the nature of the inorganic species. The catalytic activity of the unsupported nanoparticles is finally evaluated for the hydrogenation of nitrobenzene and phenylacetylene in various solvents

Streszczenie:

The objective of this project is to investigate hydrodeoxygenation (HDO), a crucial step in the treatment of bio-oil, on transition metal phosphide catalysts. The study focuses on reactions of simple oxygenated compounds present in bio-oil -- ethanol and 2-methyltetrahydrofuran (2-MTHF). The findings from this project provide fundamental knowledge towards the hydrodeoxygenation of more complex bio-oil compounds. Ultimately, the knowledge contributes to the design of optimum catalysts for upgrading bio-oil. A series of transition metal phosphides was prepared and tested; however, the focus was on Ni2P/SiO2. Characterization techniques such as X-ray diffraction (XRD), temperature-programmed reduction and desorption (TPR and TPD), X-ray photoelectron spectroscopy (XPS), and chemisorption were used. In situ Fourier transform infrared (FTIR) spectroscopy was employed to monitor the surface of Ni2P during various experiments such as: CO and pyridine adsorption and transient state of ethanol and 2-MTHF reactions. The use of these techniques allowed for a better understanding of the role of the catalyst during deoxygenation.

Streszczenie:

Solid Oxide Fuel Cell anode is readily degraded by trace amount of Phosphine (PH3) contaminant that is found in coal-derived syngas. PH3 interacts with the anode material and affects its electrochemical performance by forming secondary phases. In this paper, the influence of the ppm level of PH3 with moisture is investigated on the formation of secondary phases and hence on anode electrochemical performance degradation. Nickel yttria-stabilized zirconia (Ni-YSZ) anode shows immediate and severe electrochemical degradation due to PH3 in moist hydrogen condition attributed to the nickel-phosphate secondary phase formation. Whereas in dry hydrogen condition, nickel-phosphide is preferred to form on the anode surface that shows less deleterious effects on SOFC performance as compared to nickel-phosphate.

Streszczenie:

The improvement of reliability and reduction of overhaul time is of paramount importance to engineers involved with coatings used on gas turbine engine components. Aluminum/phosphate/chromate coatings are currently used in industrial and aircraft gas turbine engines for coating compressor components. Traditional electrolytic nickel with diffused cadmium coatings are also used but to a lesser extent. Field experience, however, has shown limitations with both coating systems, particularly in the areas of erosion, wear, and simplicity in component processability. Currently, several new electroless nickel coatings are gaining significant acceptance in the industry, both for overhaul and repair, as well as for new part manufacture. This paper presents erosion, corrosion, fatigue and stress data on these coatings. Some field experience is also presented from airline operators and overhaul facilities who are incorporating these coatings on aircraft gas turbine engine components. Information is also given on the capability of electroless nickel coatings to reduce manufacturing cost and simplify the processing of complex parts.

<div class="section abstract"><div class="htmlview paragraph">Phosphating is the most preferred surface treatment process used for auto body sheet panel before painting due to its low-cost, easy production process, good corrosion resistance, and excellent adhesion with subsequent paint layer. There are different phosphating processes used for ferrous metal like zinc phosphating, iron phosphating, di-cationic & tri-cationic phosphating, etc. Among these phosphate coatings, the best corrosion resistance and surface adhesion are achieved by tri-cationic phosphate coatings (zinc-nickel-manganese phosphate). Many new technologies of phosphating are evolving. Key drivers for this evolution are increasing demand for higher corrosion resistance, multi-metal car body processing in same phosphating bath and sustainability initiatives to reduce the carbon footprints.</div><div class="htmlview paragraph">We have evaluated two of these recent technologies. First technology being evaluated is low temperature phosphating in which phosphate bath temperature is reduced by 10°C and second is liquid activation chemicals for phosphating in which liquid phase chemical is used for activation instead of conventionally used chemical in powder form which resulted in increased activation bath life.</div><div class="htmlview paragraph">Characterization of the phosphating layer formed with these technologies on different sheets like cold rolled steel (CRS), galvanized (GI) and galvannealed (GA) steel is done using SEM and EDS techniques [<span class="xref">5</span>]. This study shows that there is significance difference in phosphate crystal size and shape formed, and this has a bearing on the surface protective performance of the coating.</div></div>

Streszczenie:

The effectiveness of ionic liquids as lubricants or additives has been recently studied for several tribological pairs: steel-steel, aluminium-steel and steel-titanium [1–2]. Likewise other materials used as engineering surfaces like nanocrystalline nickel coating [3], phosphor bronze [4], PVD coatings [5] and many others, have also been lubricated with ionic liquids in recent years. Most of these research studies are typically focused on the utilization of ionic liquids as neat lubricants. However, in economic terms, the use of ionic liquids as oil additives is more convenient because of its high cost.
