A highly active and selective Au@UIO-67 catalyst has been assembled. Gold nanoparticles (AuNPs) are monodispersed on the UIO-67 surface of a porous metal-organic framework, the micropores in UIO-67 as templates for adsorbing Au ions and enhancing interaction between AuNPs and UIO-67, favoring the formation of isolated and well-dispersed AuNPs. The catalyst exhibits high catalytic activity and CO selectivity for the reverse water-gas shift reaction in a fixed-bed flow reactor.
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.
