Abstract
With the rapid development of modern society, the efficient development and utilization of new energy have become more and more important. The development of high-performance energy storage and conversion devices has a decisive impact on the sustainable and efficient use of energy. In the foreseeable future, the exploration of high-quality functional materials for energy storage and conversion will continue to be the main goal pursued by the scientific and application fields. Metal organic frameworks (MOFs) have the merits of adjustable porosity and a stable structure. Moreover, the metal elements in the MOFs could play a role as active sites during the electrochemical process. Thus, various kinds of MOFs and their derivatives have been prepared and used as functional materials for energy storage and conversion. In this work, the applications and potentials of cobalt-based MOFs (Co-MOFs) and their derivatives in supercapacitors, advanced batteries, and electrochemical catalysts have been reviewed and summarized. The electrochemical properties, energy storage and conversion mechanisms, and the effects on performance were described in depth. A large number of Co-MOFs with unique structures, as well as numerous Co-MOF derivatives and composites, have been developed, and excellent application performance has been achieved, which have already become some of the most advantageous functional materials in the energy storage and conversion field. In addition, the current research status, difficulties, and prospects of Co-based MOFs and their derivatives as energy storage and conversion functional materials were comprehensively summarized at the end of this study.
