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 ...

Analysis and comparison of hydrogen routes for automotive use

Peter Loveday

The goal of this project would be to analyze and compare systematically the different existing and emerging processes producing hydrogen from fossil and renewable resources. As the perspective would be the replacement of fossil fuels with hydrogen in the t ...

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

Novel catalytic applications of carbon nanofibers on sintered metal fibers filters as structured supports

Marina Ruta

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 ...

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). ...

A viable hydrogen-storage system based on selective formic acid decomposition with a ruthenium catalyst

Paul Joseph Dyson, Gabor Laurenczy, Céline Fellay

The use of formic acid as a hydrogen-storage material has become more feasible thanks to the development of a homogeneous catalytic system of ruthenium water-soluble complexes (Ru/TPPTS; TPPTS=meta-trisulfonated triphenylphosphine) that selectively decompo ...

Generation of OH radicals at palladium oxide nanoparticle modified electrodes, and scavenging by fluorescent probes and antioxidants

Hubert Girault, Junqiu Liu

The reduction of palladium oxide nanoparticles in the presence of hydrogen peroxide or dissolved oxygen gives rise to a catalytic reduction current dependent on the hydrogen peroxide concentration or the oxygen concentration. Using terephthalic acid as an ...

Reactivity and Catalytic Activity of a Robust Ruthenium(II)-Triphos Complex

Paul Joseph Dyson

The ruthenium(II)-triphos acetato complex [RuCl(OAc)(k3-triphos)] (triphos = (PPh2CH2)3CMe) has been found to be an active catalyst precursor for the hydrogenation of 1-alkenes under relatively mild conditions (5-50 bar H2, 50 °C). In contrast to related t ...

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 ...

Promoting Role of [PtI2(CO)]2 in the Iridium-Catalyzed Methanol Carbonylation to Acetic Acid and Its Interaction with Involved Iridium Species

Gabor Laurenczy

The catalytic activity of the iridium complexes involved in methanol carbonylation is significantly enhanced when the carbonyliodoplatinum dimer [PtI2(CO)]2 (10') is added to the reaction mixt. Under CO this complex readily affords th ...
