Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

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 ...

Hydrogen holds the potential to be an alternative to replace fossil fuels in the future. The tremendous research effort dedicated to the issue of hydrogen storage has led to considerable advancements in the development of both adsorption materials and chem ...

The hydrogenation of phenylacetone to cyclohexylacetone, in which the aromatic ring is selectively reduced in preference to the carbonyl group, has been achieved with chemoselectivities exceeding 90%. The catalyst (precatalyst) used to achieve this transfo ...

Hydrogen can be generated from formic acid in aq. phase homogeneous catalytic reactions using ruthenium catalysts with water-sol. phosphine ligands. A comparison of tri-, di-, and mono-sulfonato triphenylphosphine, disulfonato diphenyl-alkyl-phosphines (Ph ...

The water-soluble ruthenium(II)–mTPPTS complex (mTPPTS= meta-trisulfonated triphenylphosphine) efficiently catalyzes the generation of hydrogen from formic acid in aqueous solution. This catalyst has been immobilized in a hydrophilic silica sup- port to fa ...

A biphasic approach to the dehydroaromatization of bioderived limonene into water-insol. p-cymene using sol. Pd nanoparticle catalysts in an aq. phase (³150 °C, 2 bar H2) was successfully achieved with a conversion of 93% and a selectivity of 82%. The Pd n ...

The efficient storage of hydrogen is one of three major hurdles towards a potential hydrogen economy. This report begins with conventional storage methods for hydrogen and broadly covers new technology, ranging from physical media involving solid adsorbent ...

The selective catalytic decomposition of formic acid into hydrogen and carbon dioxide has been achieved in water under mild conditions. For the first time, a ruthenium ion in combination with series of oligocationic, ammoniomethyl-substituted triarylphosph ...
