Description
Summary:A unique hybrid Polyoxometalate was synthesized, which can absorb visible light and perform photocatalytic activity. This Organic-Inorganic hybrid material was synthesized through attaching the organotin compound to the vacant polyoxometalate. Interestingly, this hybridization brought an outstanding decrement in the polyoxometalate band gap and turned this hybrid polyoxometalate to a photocatalytic compound, which can conduct catalytic reactions under visible light. In this line, we devised photoxidation of sulfides using this photocatalyst and under O2 atmosphere as a sustainable and environmental friendly oxidant. Various kinds of sulfides were investigated under optimum reaction conditions and the corresponding sulfoxide products were synthesized in good to high yields. [Display omitted] •Hybridization of POMs can boost their activity and improve their functions.•Taking the improvements in photonic behaviors, make the POMs good photocatalysts.•Absorption region in functionalized POMs can be shifted from UV to Visible.•Aerobic photoxidation of sulfides was done under visible light with good yields.
