Research progress on metal organic framework derived porous carbon though interfacial engineering and synergistic effect

Abstract

With the rapidly growing energy demand, supercapacitors have attracted much attention as an efficient and sustainable electrical energy storage solution. However, traditional materials have certain limitations in improving electrochemical performance and extending cycle life. Metal-organic framework (MOF)-derived porous carbons (PCs) have emerged to overcome these challenges in recent years. Due to their unique structures including high specific surface area, rich pore structure, and enhanced conductivity, they have become a research hotspot for supercapacitors electrode materials. This review provides an in-depth exploration of the widespread applications of MOF-derived PCs in the field of supercapacitors. Through various processing methods such as pyrolysis, activation, heteroatom doping, and combination with other active structures, MOF-derived PCs exhibit superior electrochemical properties. The article reviews the influences of different preparation methods and systematically analyzes their superior performance in improving maximum specific capacitance of MOF-derived PCs, achieving high-rate performance, and extending cycle life. By sorting out relevant research, it provides valuable inspiration for the future development of MOF-derived PCs in the field of supercapacitors. This research direction is expected to promote the performance improvement of supercapacitors and other electrochemical energy storage devices and contribute to the sustainable development of the clean energy field.
