“…Notably,a lthough the hydrogenation of catalyst supports can provide direct evidencef or hydrogen spillover, [3,[17][18][19][20][21] as in the case of Khoobiar's WO 3 reduction experiment, [3] its absence cannotd isprovet he presence of hydrogen spillover 'during catalysis'. From the catalytic viewpoint, hydrogen spillover can be used for varioush ydrogenation reactions if there is a' net migration' of Ha toms from the metal catalyst surface to the organic reactants.…”

“…In at least one case, where surface transport is the slow step, it has been shown that the marked effect of adsorbed water on the rate of reaction is due to its influence on the rate of diffusion (Levy and Boudart, 1974). In this paper we report the effect of coadsorbed water on the surface diffusion of stearic acid on aluminum oxide.…”

“…Perhaps dual-functional catalysts can be made more effective by addition of a component to the reaction mixture which will increase the rate of transport between sites but not otherwise influence the catalysis. Water and alcohol have been shown to play such a role in the Pt catalyzed reduction of W 0 3 (Levy and Boudart, 1974).…”

“…The latter mechanism has received considerable attention in the literature for palladium, platinum, and nickel catalysts on oxide supports (Levy and Boudart, 1974;Sermon and Bond, 1973). To our knowledge, however, hydrogen spillover has not been studied with carbon-supported catalysts.…”
