Abstract
The state of dihydrogen adsorbed on a carbon supported ruthenium catalyst has been studied by inelastic neutron scattering spectroscopy (INS) and dihydrogen adsorption by insitu experiments. At 23 K dihydrogen is adsorbed molecularly in two forms: a strongly adsorbed layer on the surface and weakly adsorbed subsequent coverage. At temperatures above 80 K some strongly adsorbed dihydrogen dissociates. INS spectroscopy is a useful insitu technique for studying adsorbed dihydrogen and its dissociation on a metal catalyst.
