This paper summarized the preparation methods of embedding or loading metal nanoparticles (MNPs) into zeolitic imidazolate frameworks (ZIFs) for constructing MNPs@ZIFs catalysts,including metalorganic chemical vapour deposition,solid grinding,solution impregnation and self-assembly,in which the advantages and disadvantages of these methods were discussed respectively,and the self-assembly was particularly introduced due to its easy control over the spatial distribution of MNPs within ZIFs in the preparation of MNPs@ZIFs catalysts. The characterization methods of MNPs@ZIFs microstructure were described,especially for the method of analyzing the spatial distribution of MNPs within ZIFs. The catalytic performance of MNPs@ZIFs in many reactions,such as coupling,oxidation and reduction,was discussed,where the selective catalysis was emphatically analyzed. Based on all above,the preparation of novel and highly stable ZIF materials with large pore sizes,the precise control of MNPs spatial distribution within ZIFs and the development of industrial preparation methods of MNPs@ZIFs were jointly proposed as the main research orientation of MNPs@ZIFs in future.
