Hydrogen storage and delivery: immobilization of a highly active homogeneous catalyst for the decomposition of formic acid to hydrogen and carbon dioxide

Paul Joseph Dyson, Gabor Laurenczy, Weijia Gan

The homogeneous catalytic system, based on water-soluble ruthenium(II)– TPPTS catalyst (TPPTS = meta-trisulfonated triphenylphosphine), selectively decomposes HCOOH into H2 and CO2 in aqueous solution. Although this reaction results in only two gas product ...

Homogeneous catalytic decomposition of formic acid for high pressure hydrogen generation

Céline Fellay

The main obstacles in the widespread use of hydrogen as energetic alternative to fossil fuels are storage problems intrinsically linked to its extremely light and explosive nature. Since no ideal storage systems currently exist, reversible fixation of hydr ...

Hydrogen production from formic acid

Paul Joseph Dyson, Gabor Laurenczy, Céline Fellay

The present invention relates to a method of producing hydrogen gas and carbon dioxide in a catalytic reaction from formic acid, said reaction being conducted in an aqueous solution over a wide temperature range and already at room temperature (25 DEG C). ...

Three-Phase Catalytic Hydrogenation of a Functionalized Alkyne: Mass Transfer and Kinetic Studies with in Situ Hydrogen Monitoring

Albert Renken, Lioubov Kiwi, Martin Grasemann

Systematic studies of mass transfer interactions with intrinsic reaction kinetics were performed for the threephase selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) over a modified Pd/CaC

Ruthenium nanoparticles intercalated in hectorite: A reusable hydrogenation catalyst for benzene and toluene

Gabor Laurenczy, André Meister

The cationic organometallic aqua complexes formed by hydrolysis of [(C 6H6)RuCl2]2 in water, mainly [(C6H6)Ru(H2O)3]2+, intercalate into sodium hectorite by ion exchange, replacing the sodium cations between the anionic silicate layers. The yellow hectorit ...

Catalytic hydrogenation of alkenes under biphasic conditions

Corinne Daguenet

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 ...

Sulfide-binding hemoglobins: effects of mutations on active-site flexibility

Majed Chergui

The dynamics of Hb I (HbI) from the clam Lucina pectinata, from wild-type sperm whale (SW) myoglobin, and from the L29F/H64Q/V68F triple mutant of SW, both unligated and bound to hydrogen sulfide (H2S), have been studied in mol. dynamics simulations. Featu ...

Acetate production from lactose by Clostridium thermolacticum and hydrogen-scavenging microorganisms in continuous culture - Effect of hydrogen partial pressure

Jean-Paul Schwitzguebel, Christophe Collet

The effect of the addition of hydrogen-consuming microorganisms on the metabolism of Clostridium thermolacticum was studied. By growing this bacterium in continuous culture at 58 degrees C, on 29 mmol lactose l(-1) (10 g l(-1)) in the feed, with the H-2-co ...

Fluorine-substituted aryllithiums

Joanna Kobylinska

Among other things, the present thesis work aimed at a rational and maximal structure proliferation. Simple arenes or heteroarenes were functionalized regioselectively through organometallic intermediates, which then may be combined with any electrophile t ...

Carbon dioxide reduction in biphasic aqueous-ionic liquid systems by pressurized hydrogen

Gabor Laurenczy

This work reports the hydrogenation of carbon dioxide/inorganic carbonate salts to formic acid/formate in two phase systems comprising an ionic phase, in which the catalyst is immobilized, and an aqueous phase in which the carbonates and formate are confin ...
