Hybrid Polyoxometalates: Merging Organic and Inorganic Domains for Enhanced Catalysis and Energy Applications

Abstract Organic–inorganic hybrids based on polyoxometalate scaffolds(POMs) are a unique class of molecular metal‐oxides featuring a composite surface, whereby the merging of complementary domains stimulates new functions and enhances performances. The interaction between the organic and inorganic components can be designed via covalent and/or non‐covalent strategies, yielding novel molecular systems with key applications in catalysis and materials science. Selected examples of such a rewarding approach will be illustrated, including the synthesis of tailored POM‐based catalysts, and their application in homogeneous systems and on electrocatalytic surfaces for water splitting and renewable energy production.
