Characterisation of adsorbed hydrogen on a novel Co/C catalyst

Abstract: Evonik Industries have recently developed a novel carbon supported cobalt catalyst. The catalyst is active for a variety of selective hydrogenation reactions and the conversion of syngas (CO+H2) into light olefins and alcohols under mild conditions. Our previous INS studies of the interaction of hydrogen with the catalyst observed an intense peak at 46 cm?1, which we assigned as the J = 0 ? 1 rotational transition of adsorbed H2. For the transition to fall to 46 cm?1 would require the H?H bondlength to increase to ~1.2 Å from 0.746 Å. Such a pronounced change in bondlength should be easily detectable by NIMROD and is the aim of this proposal. The H?H distance of H2 adsorbed on a supported catalyst has never been directly measured, so even a null result (an unchanged bondlength) is publishable. If there is a dramatic increase in the H2 bondlength, this will be a major result.
