▎ 摘　　要

Metal??organic frameworks (MOFs), a novel class of crystalline materials with the ordered porous network frameworks, are formed by the coordination of metal ions and organic bridging ligands. Because of special and unique features such as the large surface area, tunable structure and high porosity, MOFs have attracted a lot of attention in materials, environment, biomedicine and so on. However, MOFs have some disadvantages including of being easily hydrolyzed, low stability, and low electrical conductivity. It is an ideal strategy that MOFs combined with other materials to improve their features and performances. In particular, graphene shows outstanding chemical stability, good electrical conductivity, optical properties and mechanical properties. Graphene compositing with MOFs can effectively improve the photoelectric properties, stability and recyclability of MOFs. Hence, in the current paper, preparation methods of graphene / MOFs composites, including in situ growth method, interfacial growth method and blending molding method, are reviewed. We also discuss their superior performance in the fields of gas separation and storage, water purification, chemical sensors, and catalysts. Moreover, the preparation development and potential applications of graphene / MOFs composites are proposed.
