Ideal location: The active oxygen for CO oxidation on Au/TiO2 catalysts is a highly stable oxygen species, whose formation is facile and hardly activated. This species is proposed to be surface lattice oxygen at the perimeter of the Au–TiO2 interface, activated by the presence of the Au nanoparticle. At higher temperatures, thermally activated Olatt migration also gives access to adjacent Olatt species.
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.
