Dynamics and Thermodynamics of a Novel Phase of NaAlH4

Nicola Marzari

We characterize a novel orthorhombic phase (gamma) of NaAlH4, discovered using first-principles molecular dynamics, and discuss its relevance to the dehydrogenation mechanism. This phase is close in energy to the known low-temperature structure and becomes ...

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 ...

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). ...

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

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 ...

Hydrogen Sensors based on Nanoscaled Discontinuities in Palladium

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Oscar Vazquez Mena, Thomas Kiefer, Arnaud Salette

In this project we develop hydrogen sensors based on nanoscaled discontinuities (nanogaps) in palladium (Pb). These nanogaps reversibly close and open upon hydrogen/air cycling due to an increased lattice constant in the hydrated state. Therewith, an elect ...

Carbon dioxide hydrogenation on Ni(110)

Alfonso Baldereschi

We demonstrate that the key step for the reaction of CO2 with hydrogen on Ni(110) is a change of the activated molecule coordination to the metal surface. At 90 K, CO2 is negatively charged and chemically bonded via the carbon atom. When the temperature is ...

In situ NMR characterisation of an intermediate in the catalytic hydrogenation of CO2 and HCO3– in aqueous solution

Paul Joseph Dyson, Gabor Laurenczy

The water soluble ruthenium(II) complex [RuCl2(PTA)([9]aneS3)] (PTA = 1,3,5-triaza-7-phosphadamantane, [9]aneS3 = 1,4,7-trithiacyclononane) catalyzes the hydrogenation of CO2 and bicarbonate in aqueous solution. ...

Heterogeneous dehalogenation of arylhalides in the presence of ionic liquids

Gabor Laurenczy

Dehydrohalogenation of haloaromatics in ionic liquids derived from ethylmethylimidazolium or similar salts has been performed using Pd-C, Pd(OAc)2 and other catalysts using formate salts as a hydrogen source. In the ionic liquid [emim][BF4< ...
