The influence of oxygen on the surface interaction between CO2 and copper studied by ambient pressure X-ray photoelectron spectroscopy

Abstract:

Copper materials are widely used in heterogeneous catalysis, including CO2 reduction, but the precise mechanisms and the oxidation states of Cu involved remain controversial. The surface chemistry at the interface between solid Cu and the CO2 containing gas phase lies at the heart of the complex pathways involved in the catalytic interaction. This paper utilizes the technique of ambient pressure X-ray photoelectron spectroscopy (APXPS) to probe the surface chemistry of polycrystalline Cu in a...
