Advances in electrochemistry of intrinsic conductive metal-organic frameworks and their composites: Mechanisms, synthesis and applications

Abstract

As a widely explored porous coordination polymer, metal-organic frameworks (MOFs) have great potential application in catalysis, sensing, gas storage and separation, their inherent poor conductivity limit their application in electrochemical domains. Therefore, the researchers introduced π-conjugated organic ligands to obtain conductive MOFs, presenting not only rich pores but also good conductivity. Review paper about synthesis and application of MOFs and MOF derivatives is hardly new. However, there are few reports on intrinsic conductive MOFs. In this paper, we review the charge transfer mechanism and preparation of intrinsic conductive MOFs, as well as their latest research advance in electrochemistry, including electrocatalysis, supercapacitor and sensing. In addition, the trends and challenges of conductive MOFs are also discussed. This paper provides a reference for the research of conductive MOFs in the field of electrochemistry.
