摘要：
A Rh/ZrO2 catalyst has been studied in the hydrogenation of CO in an in situ IR cell operating at high temperature and pressure, and using FTIR to follow the formation of surface and gas phase species as a function of reaction time. The reaction between CO and hydrogen was studied by varying the catalyst reduction temperature, reaction temperature, total pressure and hydrogen/CO ratio. Surface species identified were carbonyls on the rhodium surface, formates, carbonates and hydrocarbons. The relationship between adsorbed carbonate and formate is discussed in detail.
