AbstractThe effects of Fe promoter on the desorption and hydrogenation of adsorbed CO over a series of silica-supported Rh-based catalysts were investigated by means of temperature-programmed desorption of adsorbed CO (CO-TPD) and temperature-programmed surface reaction (TPSR) of adsorbed CO with hydrogen. There were three peaks of CO desorption in the CO-TPD spectra over the Rh/SiO2, catalyst. The low-temperature peak of CO desorption was unchanged and the two high-temperature peaks shifted simultaneously toward lower temperature and became narrower when 0.05% of Fe was added into Rh/SiO2. In contrast, the desorption peaks at high temperature moved to higher temperature when 0.05% of Fe was added into the Rh-Mn-Li/SiO2 catalyst, and the amount of CO desorption was more than that over Rh/SiO2. However, the amount of CO desorption decreased with increasing amount of Fe added. The temperature of maximum methane formation in the TPSR spectra was found to be in the following order: Rh/SiO2(482 K)
