Title: Preparation and photocatalytic activity of high-efficiency visible-light-responsive photocatalyst SnS{sub x}/TiO{sub 2}

Abstract

Visible-light-responsive composite photocatalysts SnS{sub 2}/TiO{sub 2} and SnS/TiO{sub 2} with different mass ratios were prepared by in-situ synthesis technology in solution with commercial TiO{sub 2}. The junction-based materials SnS{sub x} (x=1, 2)/TiO{sub 2} were found to have high visible-light photocatalytic performance and possess much better activity than the single-phase SnS{sub x} or TiO{sub 2}. The greatly enhanced photocatalytic activity of the SnS{sub x}/TiO{sub 2} composites was mainly attributed to the matching band potentials and efficient charge transfer and separation at the tight-bonding interface between SnS{sub x} and TiO{sub 2}. The fact was confirmed by the comparison of photocatalytic activities of the SnS{sub 2}/TiO{sub 2} samples prepared by physical mixing method and in-situ synthesis technique. - Graphical Abstract: Visible-light-responsive composite photocatalysts SnS{sub 2}/TiO{sub 2} and SnS/TiO{sub 2} with different mass ratios were prepared by in-situ synthesis technology in solution with commercial TiO{sub 2}.
