摘要: Abstract Coadsorption of carbon monoxide (CO) with water on Pt(111) was investigated by cyclic voltammogram (CV), in-situ and non-situ IRAS STM in order to explore the mechanism oxidation CO 2 surface. adsorbed a electrode at 0.4 V (RHE) showed strong interaction overlayer molecules retarded , whereas 0.05 started oxidize lower potential. The structure change from (2 × 2)-3CO ( θ = 0.75) (√19 √19)R23.4−13CO 0.685) followed an adsorption water, which played important role oxidation. Under UHV c(4 2) 0.50) observed preference compression structures because absence coadsorbed molecule.
