Polyoxometalate‐Based Metal Organic Frameworks: Recent Advances and Challenges

Abstract

Abstract Polyoxometalates (POMs) are stable metal anion clusters formed by pre‐transition metal elements in their highest oxidation state, with rich chemical composition and diverse structures. However, the highly dispersed structure makes it difficult to perform catalytic activity in a stable manner. Metal‐organic frameworks (MOF) with high specific surface and topological structure are a unique class of solid porous materials based on metal ions or metal clusters and organic ligands. In recent years, numerous studies have combined these two as POMOF composite nanoplatform, which not only retains the advantages of them but also ameliorates the shortcomings. With active reactivity, high stability and large specific surface area, this synergistic and complementary combination makes it a promising composite nanomaterial. This mini‐review presents the applications of POMOFs in different fields, including combating environmental problems and energy crises, catalyzing organic reactions, biosensors and supercapacitors, and presents the prospect of future work of POMOFs.
