Abstract
Methane oxidation to formaldehyde was studied over a vanadium oxide ca talyst supported on silica at 630-degrees-C using the technique known as temporal analysis of products with sequential pulsing of methane an d oxygen. This work shows that methane interacts very weakly and oxyge n very strongly with the catalyst surface and it is concluded that the initial activation of methane involves an adsorbed oxygen species. Me thyl radicals formed in the first step subsequently extract lattice ox ygen to yield formaldehyde.
