Metal Organic Frameworks as Robust Host of Palladium Nanoparticles in Heterogeneous Catalysis: Synthesis, Application, and Prospect

Abstract

Metal organic frameworks (MOFs) is one set of the most excellent supports for Pd nanoparticles (NPs). MOFs as the host, mainly have the following advantages: (i) provide size limits for highly dispersed Pd NPs; (ii) fixing Pd NPs is beneficial for separation and reuse, avoiding the loss of expensive metals; (iii) the MOFs skeleton is diversified and functionalized, which is beneficial to enhance the interaction with Pd NPs and prolong the service life of the catalyst. This review discusses the synthesis strategy of [email protected], which provides guidance for the synthesis of similar materials. After that, the research advance of [email protected] in heterogeneous catalysis is comprehensively summarized, including C–C coupling reaction, benzyl alcohol oxidation reaction, simple olefin hydrogenation reaction, nitroaromatic compound reduction, tandem reaction, and the photocatalysis, with the emphasis in providing a comparison with the performance of other alternative Pd-containing catalysts. In the final section, this review presents the current challenges and which are the next goals in this field.
