Research and Application of Co-MOFs and Their Derived Materials in Supercapacitors
Cobalt-based metal-organic frameworks(Co-MOFs)have been extensively studied in the field of energy storage and conversion because of their advantages of large specific surface area,high porosity and tunable structure.However,poor electrical conductivity is the main obstacle to the large-scale application of Co-MOFs,and improving the electrical conductivity of Co-MOFs materials is significant and challenging for their supercapacitor applications.The modification of Co-MOFs and the preparation of derivative materials can not only make up for the defect of low conductivity,but also have the advantages of high porosity,unique morphology and rich channels.This paper analyzes and compares the electrochemical properties of Co-MOFs and their derived carbon materials,oxides,sulfides,phosphides and hydroxides and corresponding composites with the research progress in recent years,which can help the researchers to understand the structural design of Co-MOFs and their derived materials,and provide a reference for their application in supercapacitors.
