CO adsorption on RhPd(100) from UHV to elevated pressure

Abstract

RhPd bimetallic alloys are regarded as promissing substances for high catalytic activity in CO oxidation reaction, nevertheless the adsorption behavior on the surface are still missing. In this work, we investigated the CO adsorption on RhPd(100) single-crystal from UHV to elevated pressure up to 1 Torr, using polarlization modulation infrared reflection absorption spectroscopy (PM-IRAS) and ambient pressure X-ray photoelectron spectroscopy (AP-XPS).
