Given several advantages of metal–organic frameworks (MOFs) including regular porosity, ultrahigh specific surface area, and periodic intra-framework functionality, MOFs have been considered as desirable materials for various electrochemical applications including electrocatalysis, electroanalysis, and energy storage. However, the electrically insulating nature and relatively poor chemical stability of most MOFs strongly limit the use of pristine MOFs in these applications.<br/>In this talk, various strategies that render the use of chemically stable MOF-based materials for electrochemical energy storage, electrocatalysis as well as the design of proton conductors developed by our research group in 2021 will be highlighted. The use of highly water-stable group (IV) metal-based MOFs, including the Zr(IV)-based MOFs and Ce(IV)-based MOFs, would ensure their structural integrity during electrochemical operations, and the design of electrically conductive MOF-carbon and MOF-conducting polymer nanocomposites would further facilitate the interparticle electrical conduction between MOF crystals. With such rational material designs, these electronically conducting MOF-based nanocomposites could provide enhanced performances in supercapacitors as well as act as remarkable electrocatalysts for electrochemical oxygen evolution.
