Application of Metal‐Organic Framework Composites

Environmental issues have intensified, and demand for energy continues to grow, making it challenging for conventional materials to meet the needs of further exploration in these fields recently. Metal‐organic frameworks (MOFs) offer considerable promise for such endeavors owing to their multichannel architecture, large specific surface area, and multifunctional structures. Unfortunately, the inherent instability and unsatisfactory conductivity of original MOFs pose unavoidable challenges in practical applications. Therefore, composites based on MOFs retain the advantages of original MOFs while integrating the functionalities of guest materials (including inorganic carbon materials, metal oxides, and polymers, etc.), are emerging as frontrunners in the future of energy, environment, and biomedical sciences. This article provides a comprehensive review of the applications of MOF composites across various fields, including adsorption, energy storage, catalysis, biomedicine, and sensors. Additionally, it analyzes the physical and chemical properties of various composites based on MOFs from a dimensional viewpoint. In this regard, we not only emphasize the advantages of MOF composites but also provide a detailed analysis and objective overview of their application effects, offering innovative solutions to global challenges.
