摘要：The Zn-based metal-organic framework (MOF) catalysts MOF-74, Au@Pd@MOF-74, Pt/MOF-74, and Pt/Au@Pd@MOF-74, were assembled. Core-shell Au@Pd, in which Au nanoparticles (NPs) serve as the core for the epitaxial growth of Pd shells, was encapsulated into MOF-74 nanoshuttles to control the MOF-74 morphology and impart NP functionality. Pt NPs were loaded onto the MOF-74 surface. Pt/MOF-74 catalyzed CO2 conversion at 99.7% CO selectivity in the reverse water-gas shift (RWGS) reaction, and Au@Pd@MOF-74 photocatalyzed CO2 with 100% CO selectivity. Importantly, the catalyst Pt/Au@Pd@MOF-74, not only catalyzed the conversion of CO2 to CO in RWGS with 99.6% selectivity, but also photocatalyzed CO2 to CH4 at low concentration (800 PPm) (C) 2018 Elsevier Inc.
