Summary: Nanotechnology is an active research field in materials science, with metal-organic frameworks (MOFs) and graphene oxide (GO) being two important areas of study. MOFs offer a large specific surface area, high porosity, pore size flexibility, post-synthesis modification, and thermal stability. Similarly, GO has a comparable surface area to MOFs and the advantages of amphiphilicity and dispersion in water. The combination of MOFs and GO has attracted attention due to its resemblance to metal ions and organic binding linkers, as well as its superior performance compared to MOFs or GO alone. This review provides a summary of recent research on the properties, synthesis techniques, advantages, challenges, and various applications of MOFs/GO composites, including supercapacitors, gas separation and storage, water purification, sensing, catalysis, and biomedical applications.

Summary: The rapid development of electric vehicles and mobile electronic devices is driving the improvement of advanced high-performance lithium ion batteries (LIBs). The capacity, rate performance and cycle stability of LIBs directly depend on the electrode materials, with anode materials being of more urgent concern than cathode materials. Challenges still exist in industrial production of anode materials superior to commercial graphite.
