Based on a detailed mechanism of the oxidative dehydrogenation of light alkanes and the oxidation of methanol to formaldehyde the effect of different supporting oxides such as SiO2, Al2O3, ZrO2, and CeO2 on the activity of supported vanadium oxides is analyzed. The remarkably high activity observed for vanadia catalysts supported on ceria directly relates to a special synergy between the ceria support and the supported oxide (vanadia). Experimental model catalysts such as thin films and gas phase clusters have been crucial in reaching these conclusions.
