Research advances of light-driven hydrogen evolution using polyoxometalate-based catalysts

With the increasing concerns to energy shortage and environmental problems in modern society, development of cheap, clean, sustainable alternatives has been attracting tremendous attention globally. Among various strategies renewable exploration, solar-driven water splitting into its compositional elements H2 O2 is an ideal approach convert store solar chemical bonds. In recent few decades, as emerging new type catalysts, polyoxometalates (POMs) have widely utilized for due their versatile synthetic methodology highly tunable physicochemical photochemical properties. This critical review addresses research advances light-driven hydrogen evolution using polyoxometalate-based including plenary POMs, transition-metal-substituted POM@MOF composites, POM-semiconductor hybrids, under UV, near UV visible light irradiation. addition, catalytic mechanism each reaction system thoroughly discussed summarized. Finally, a comprehensive outlook this area also prospected.
