Abstract
The state of dihydrogen adsorbed on a carbon supported ruthenium catal yst has been studied by inelastic neutron scattering spectroscopy (INS ) and dihydrogen adsorption by in situ experiments. At 23 K dihydrogen is adsorbed molecularly in two forms: a strongly adsorbed layer on th e surface and weakly adsorbed subsequent coverage. At temperatures abo ve 80 K some strongly adsorbed dihydrogen dissociates. INS spectroscop y is a useful in situ technique for studying adsorbed dihydrogen and i ts dissociation on a metal catalyst.
