Monodispersed gold nanoparticles supported on a zirconium-based porous metal-organic framework and their high catalytic ability for the reverse water-gas shift reaction.

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.
