摘要/描述

A Raman cell suitable for the study of solid/liquid/gas three-phase systems and that can work very efficiently onconfocal microprobe Raman systems was introduced. The influence of the environment on the adsorption behavior ofmodel molecule CO on Pt was investigated and different behaviors were observed in the aqueous solution compared tothe gas phase. A preliminary Raman measurement on the three-phase system was performed using methanol as a testingsolution. The diffusion of CO, a dissociate product of methanol, on the Pt electrode from the solution side to the gasside was observed.
