Visible light induced dye-sensitized photocatalytic hydrogen production over platinized TiO2 derived from decomposition of platinum complex precursor

► C-Pt/TiO2 is found to be a high active photocatalyst in visible region. ► For H2 production, the photocatalytic activity is enhanced more than 3 times. ► Small-size and well-disperse platinum particles is verified by TEM measurement. ► Surface-anchored Pt complex reduction is confirmed to be a promising technique.
