Heterogeneous Catalytic Reactor for Hydrogen Production from Formic Acid and Its Use in Polymer Electrolyte Fuel Cells

Gabor Laurenczy, Nordahl Autissier, Katerina Stefania Sordakis, Martin Grasemann, Andrew Francis Dalebrook

A proof-of-concept prototype of a medium-scale heterogeneous catalytic reactor for continuous production of hydrogen through formic acid (FA) dehydrogenation has been developed. A commercial proton exchange membrane (PEM) fuel cell (FC) fed with the result ...

Regioselective Nitration and/or Halogenation of Iridabenzofurans through Electrophilic Substitution

Andrew Francis Dalebrook

Regioselective electrophilic substitution reactions of the iridabenzofurans [Ir(C7H5O{OMe-7})(CO)(PPh3)(2)]-[OTf] (1) and IrCl(C7H5O{OMe-7})(PPh3)(2) (2) provide a convenient route to mononitro-, dinitro-, and mixed nitro-/halo- substituted derivatives. Tr ...

Quantitative aqueous phase formic acid dehydrogenation using iron(II) based catalysts

Gabor Laurenczy, Andrew Francis Dalebrook, Mickael Montandon-Clerc

We present here the results of our investigation on aqueous phase formic acid (FA) dehydrogenation using non-noble metal based pre-catalysts. This required the synthesis of m-trisulfonated-tris[2-(diphe nylphosphino)ethyl]phosphine sodium salt (PP3TS) as a ...

A Viable Hydrogen Storage and Release System Based on Cesium Formate and Bicarbonate Salts: Mechanistic Insights into the Hydrogen Release Step

Gabor Laurenczy, Katerina Stefania Sordakis, Andrew Francis Dalebrook

Aqueous solutions of cesium formate and bicarbonate repre- sent an effective hydrogen storage–delivery couple that under- goes either release or take up of hydrogen in the presence of {RuCl2(mTPPTS)2}2 (TPPTS = triphenylphosphine trisulfonate) and excess m ...

Formic Acid Dehydrogenation Catalysed by Tris(TPPTS) Ruthenium Species: Mechanism of the Initial "Fast" Cycle

Gabor Laurenczy, Andrew Francis Dalebrook, Arnaud Thevenon, Ewan Patrick Frost-Pennington

Water-soluble ruthenium m-triphenylphosphinetrisulfonate (TPPTS) complexes are excellent catalysts for formic acid dehydrogenation. Interestingly, the choice of metal catalyst precursor has a direct influence on initial activities. The reaction with hexaaq ...

Hydrogen storage: beyond conventional methods

Gabor Laurenczy, Martin Grasemann, Weijia Gan, Séverine Joëlle Moret, Andrew Francis Dalebrook

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 ...
