Hydrogen spillover refers to the diffusion of surface hydrogen species from metal sites where they are produced by the dissociation of hydrogen molecules to an oxide support that has no activity for dissociative hydrogen adsorption. In this paper, the existence of hydrogen spillover and its contribution in the hydrogenation reaction is demonstrated.The positive effects of hydrogen can find application in many industrial applications such as hydroprocessing, isomerisation and reforming. It can also be used for membrane manufacture to increase the permeability and permselectivity of hydrogen.
