High-performance effective metal–organic frameworks for electrochemical applications

Abstract

Metal–organic frameworks (MOFs) are a versatile category of porous coordination polymers which can be differentiated from other porous nanomaterials due to their fascinating properties such as adaptable surface chemistry, tuneable functionalities, and exceedingly large surface area and uniform/controllable pore size. This newly emerging family of materials with such extraordinary attributes has generated strong research interest, making pristine MOFs and MOF based hybrids a potential platform for a diverse range of applications. However, inferior electrical conductivities and poor chemical stabilities in aqueous solutions have narrowed MOF's application base. In this review article, recent advancement in the synthesis techniques of MOFs and the impact of various production parameters on their physical, chemical, and electrochemical characteristics have been discussed in detail. In addition, their electrochemical performance in rechargeable batteries, supercapacitors, fuel cells and electrochemical sensors has been discussed briefly. Furthermore, future research direction and anticipated challenges have also been reviewed.
