:Oxygen is known to change drastically the surface states and the catalytic properties of transition metal carbides. In order to better understand the mechanism of the reaction of hydrocarbons with the oxygen modified surfaces, surfaces have been prepared by controlled additions of oxygen on a clean WC carbide. 2-methylpentane and n-butane were reacted on these surfaces. The obtained results have been compared with those observed on metal, oxygen predosed metal, and partially reduced oxide. A on the oxygen modified surfaces.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
