A computational study of CO oxidation reactions on metal impurities in graphene divacancies

Abstract

molecules on Mo-DG substrate has a much smaller energy barrier, and the generation of atomic oxygen is active for CO oxidation. These results indicate that the varied adsorption behaviors of reactive gases on M-DG substrates can determine the catalytic pathways and energy barriers, which give us insight into the surface reactivity of graphene-metal composite catalysis in energy-related devices.
