Abstract
Adsorbed water facilitates sulfidation of oxidic molybdate/alumina cat alysts. The mode of binding and the role of water in the catalyst has been investigated by an inelastic neutron scattering (INS) study of th e librational modes of the bound water. Water is adsorbed associativel y at molybdenum centres in calcined molybdate/alumina. The role of the adsorbed water in aiding sulfidation is discussed.
