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.
一种高活性和高选择性的Au@UIO-67催化剂已被制备出来。金纳米颗粒（AuNPs）单分散在多孔金属有机骨架UIO-67的表面，UIO-67中的微孔作为吸附金离子的模板，并增强AuNPs与UIO-67之间的相互作用，有利于形成孤立且分散良好的AuNPs。该催化剂在固定床流动反应器中对逆水煤气变换反应表现出高催化活性和对一氧化碳的选择性。
