摘要：

Infrared spectra are reported of CO(5 atm) and CO(5 atm)/H2(10 atm) over Rh/SiO2 catalysts at high temperatures. Three stages of reaction involved initial CO adsorption, followed by the appearance of a band ascribed to a reactive hydrocarbonaceous residue, and finally the slow generation of methane, adsorbed methoxy and ethoxy groups and a methylene-containing hydrocarbon product. The alkoxy groups existed predominantly on the surface of the silica support.
