Bonding of H to Ni, Pd, and Pt Surfaces
Abstract
The bonding of H to the (111) surfaces of Ni, Pd, and Pt has been studied with use of angle-resolved photoelectron spectroscopy. H adsorbed onto a cooled substrate produces photoemission spectra characteristic of chemisorption. In this state the H atoms form an ordered overlayer. Heating the chemisorbed layer to ~ 300 K results in an irreversible transition of the H atoms into a subsurface site.
