All-inorganic POM cages and their assembly: A review

Searching for suitable methods to construct all-inorganic cage materials by using polyoxometalates (POMs) as secondary building units (SBUs) has been of great interest, because such materials not only exhibit fascinating cage-shaped structures and unique physicochemical properties derived from both cage architectures and POM clusters, but also have promising and practical applications in areas of mole-cule separation, guest recognition, molecular reactors, photocatalysis, environmental protection, and so on. In this review, the recent development in all-inorganic POM-based cage materials is summarized, including their assembly methods, structures, properties, and related applications. Moreover, the current challenges in the design and assembly of all-inorganic POM cages as well as the development potential of this area also discussed. (c) 2023 Elsevier B.V. All rights reserved.
