Heterogeneous Silica-Supported Ruthenium Phosphine Catalysts for Selective Formic Acid Decomposition

Paul Joseph Dyson, Gabor Laurenczy, Weijia Gan

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 ...

Impurity Gas Analysis of the Decomposition of Complex Hydrides

Andreas Züttel, Shunsuke Kato, Elsa Callini

This study aims at an investigation of the impurity gases emitted during the decomposition of borohydrides. For this we have set up a quantitative gas analysis based on a combination of FTIR spectroscopy and gravimetry. We show that the emission of various ...

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 ...

Selective Formic Acid Decomposition for High-Pressure Hydrogen Generation: A Mechanistic Study

Paul Joseph Dyson, Gabor Laurenczy, Ning Yan, Céline Fellay

A homogenous catalytic system has been developed that efficiently and selectively decomposes formic acid into hydrogen and carbon dioxide. [Ru(H2O)6]2+, [Ru(H2O)6]3+ and RuCl3·xH2O are all excellent precatalysts in presence of TPPTS (TPPTS=meta-trisulfonat ...

A DEMS study of methanol and formic acid oxidation on boron-doped diamond electrode

Christos Comninellis, György Foti, Agnieszka Kapalka

The electrochemical oxidation of methanol and formic acid in 1 M HClO4 is studied on boron-doped diamond electrode using differential electrochemical mass spectrometry (DEMS). DEMS is used to identify products and intermediates of the reaction monitored on ...

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 ...
