Advances in Graphene Oxide/MOFs Composites

金属有机骨架(MOFs)是一种晶态多孔材料，具有超高的比表面积、极高的孔隙率、可变的孔径和多样的功能位点。氧化石墨烯(GO)是石墨烯的氧化衍生物，具有独特的二维层状结构和丰富的含氧官能团，表现出优异的亲水性、分散性和化学可修饰性。这些特性使GO成为MOFs负载的理想基底，GO与MOFs的复合材料因其协同效应成为研究热点，MOFs的多孔性和可设计性也进一步拓展了复合材料的功能。本文综述了GO/MOFs复合材料的制备方法(如原位生长、自组装和物理混合等)及其在CO2吸附、污水处理、超级电容器和生物医学等领域的应用进展，并探讨了当前面临的挑战和未来发展方向。Metal-organic skeletons (MOFs) are crystalline porous materials with ultra-high specific surface area, very high porosity, variable pore size and diverse functional sites. Graphene oxide (GO) is an oxidised derivative of graphene with a unique two-dimensional layered structure and an abundance of oxygen-containing functional groups, exhibiting excellent hydrophilicity, dispersibility and chemical modifiability. These properties make GO an ideal substrate for MOFs loading, and composites of GO and MOFs have become a research hotspot due to their synergistic effect, and the porousness and designability of MOFs further expand the functionality of the composites. This paper reviews the preparation methods of GO/MOFs composites (in situ growth, self-assembly, and physical mixing) and their advances in CO2 adsorption, wastewater treatment, supercapacitors, and biomedicine, and discusses the current challenges and future directions.
