Biography

Gábor Laurenczy finished his studies (MSc, chemistry) at the Kossuth University, Debrecen – Hungary in 1978, three years later he obtained a PhD (inorganic chemistry). In 1985 he became assistant professor (Dept. of Inorganic Chemistry) and in 1991 he made his habilitation (Hungarian Academy of Sciences). In 1985 he moved to Switzerland where in 1991 he became assistant professor at the University of Lausanne and from 2001–2009 he was master of teaching and research at EPFL. Since 2010 he has been a professor at École Polytechnique Fédérale de Lausanne and head of the Group of Catalysis for Energy and Environment.

Heterogeneous Ruthenium Catalysts for Hydrogen Generation from Formic Acid

HCOOH can be selectively decomposed into CO free carbon dioxide and hydrogen.[1-3] It has
been shown, that beside the ruthenium(II)-mtppts systems,[4] the iron(II) – hydrido tris[(2-diphenylphosphino)
ethyl]-phosphine complex also catalyses formic acid cleavage with an exceptionally
high rate and efficiency.[5] Sustainable hydrogen storage[1, 6] have been developed based on the
hydrogenation of bicarbonates, or CO2.

The water soluble ruthenium(II) – (mTPPTS) (mTPPTS= meta trisulphonated triphenylphosphine)
catalysts were immobilized in a hydrophilic silica support to facilitate mobile, portable
applications.[7] A series of heterogenized catalysts have been prepared using derivatized silica.
The length of the alkylene chain separating the silica from the diphenylphosphine group has been
varied in these catalysts, all of them catalyzing the decomposition of formic acid. The catalysts
were easily separated from the solution and reused. The optimized catalytic systems exhibited an
activity and stability comparable to the homogeneous catalysts.
