Recent advances on high-nuclear polyoxometalate clusters

The design and construction of high-nuclear polyoxometalate (POM) clusters remain a severe challenge, but attract significant interest on account of their impressive structural versatility and outstanding prop-erties in nanosized dimensions. With continuous exploration, diverse synthetic strategies have been developed that open multiple windows for constructing and engineering abundant high-nuclear POM species with function-oriented applications. Remarkably, the unique behaviors of Mo, W, V, Nb and Ta have demonstrated the promise of POMs in fabricating distinct architectures (from giant molecular metal oxides to metal-organic polyhedra) and applications (from catalysis, electrode materials, proton conduc-tivity, magnetism, luminescence to molecular recognition and gas separation, etc.). This review summa-rizes recent advances on high-nuclear POM clusters, highlighting synthetic strategies, structural classifications and relevant applications in different areas. Furthermore, challenges and prospects of high-nuclear POM clusters are presented.(c) 2022 Elsevier B.V. All rights reserved.
