摘要：
The hydrogenation of CO adsorbed on Pd/Al2O3 can proceed through the formation of a methoxy species on the Al2O3 support by spillover. The rate of formation of the methoxy species and the effect of coadsorbed water on CH3O hydrogenation are presented. Methoxy hydrogenates faster than CO adsorbed on Pd, and though H2O decreases the rate of spillover, methoxy hydrogenation may contribute to the high rate of steady state methanation observed on Pd/Al2O3.
