Abstract  The adsorption and reaction of methanol on Cu and ZrO2/Cu were investigated using in situ infrared diffuse reflectance spectroscopy, in which the catalysts were reduced at different temperatures in order to change the content of surface oxygen species and investigate the change trends of methanol adsorption and reaction over the catalysts with the oxygen species content. The results show that methanol is adsorbed on the surface of Cu to produce CO2 via the intermediate of adsorbed formaldehyde, while the intermediate of formate is formed on the surface of ZrO2/Cu. The production rate of CO2 via the intermediate becomes slower with the rise of the reduction temperature of the catalysts, illustrating that the content of oxygen species on the surface of the catalysts determines the formation of the intermediate and the reaction rate.

Key words： Methanol adsorption      In situ infrared diffuse reflectance      Cu      ZrO2/Cu
