Abstract

This article investigates the adsorption of hydrogen on the Pd(111) surface and on the Pd(110) plane to determine the possible differences in adsorption dynamics on a smooth and a corrugated surface. The energy dependence and the angular variation of the initial sticking coefficient were also taken into consideration. The results indicate that the adsorption of hydrogen onto palladium occurs in parallel processes through a direct path and a precursor path. There is relatively little difference in the adsorption properties of the (111) and the (110) plane; the appearance of a molecular precursor on the (111) plane is related to the electronic structure of palladium.
