Supported metal catalysts are important from both an industrial and a scientific point of view. They are used, amongst others, in large-scale processes such as catalytic reforming, hydrotreating, polymerization reactions and hydrogenations. Often, these ca ...
The water soluble ruthenium(II) complex [RuCl2(PTA)([9]aneS3)] (PTA = 1,3,5-triaza-7-phosphadamantane, [9]aneS3 = 1,4,7-trithiacyclononane) catalyzes the hydrogenation of CO2 and bicarbonate in aqueous solution. ...
Ruthenium(II)-arene diphosphine complexes are shown to be effective precursors for the catalytic hydrogenation of the C=C bond in an aqueous biphase using molecular hydrogen as the hydrogen source. A mechanistic study performed in water, utilizing high gas ...
Reaction pathways during CO2 hydrogenation catalyzed by the Ru dihydride complex [Ru(dmpe)2H2] (dmpe=Me2PCH2CH2PMe2) have been studied by DFT calculations and by IR ...
Aminosilane solutions with pH equal to 8 and to 11 were applied and cured on SiO2 coated poly(ethylene terephthalate) (PET) films. The permeability of the silane-silica hybrid coating on PET was reduced twofold compared to that of the SiO2/PET film, at sol ...
The reactions of (eta(6)-C6H6)RuCl2 and (eta(6)-p-cymene)RuCl2 With hydrogen in the presence of the water-soluble phosphines tppts (meta-trisulfonated triphenylphosphine) and pta (1,3,5-triaza-7-phosphaadamantane) afforded as the main species [(e ...
The water-soluble iridium(III) complexes [CpIr(PTA)Cl2] (1) and [CpIr(PTA)2Cl]Cl (2) (PTA = 1,3,5-triaza-7-phosphaadamantane) have been synthesised and characterised by spectroscopy and X-ray crystallography. The complexes were evaluated as catalyst prec ...
This work covers homogeneous and biphasic catalysis in ionic liquids and water. The work presented herein is divided into two major parts: catalytic hydrogenation and catalytic hydroformylation. The first part also serves as an introduction to catalysis in ...
The electrostatic, hydrodynamic and conformational properties of aqueous solutions of succinoglycan have been analyzed by fluorescence correlation spectroscopy (FCS), proton titration, and capillary electrophoresis (CE) over a large range of pH values and ...
To study the physicochemical properties of the DTTA chelating moiety (H4DTTA = diethylenetriaminetetraacetic acid = N,N′-[iminobis(ethane-2,1-diyl)]bis[N-(carboxymethyl)glycine]), used in several compounds proposed as magnetic resonance imaging (MRI) contr ...
