Abstract
A platinum single crystal electrode with ordered step and terrace structures was used to probe site-dependent aspects of methanol surface chemistry. Infrared spectral features of the adsorbed CO reaction intermediate were measured in parallel experiments with Pt(335) (Pt(s)-[4(111) × (100)]) and Pt(111) electrodes. Experiments confirm that methanolic CO formation is inhibited at Pt(111) at potentials in the hydrogen adsorption region, and they reveal that methanol dissociative chemisorption proceeds to a limited extent in this potential region at the corrugated Pt(335) surface plane, where independent vibrational spectral features for CO at step and terrace sites were detected.
