Abstract
A new organic-inorganic photosensitive coordination compound [RuL(bpy)2](PF6)2 (to represent by TM1) had been synthesized by reaction of L (LÂ =Â 2-hydroxyl-5-(imidazo-[4,5-f]-1,10-phenanthrolin) benzoic acid) with bipyridyl ruthenium, and further characterized by UV-vis, IR, NMR MS and CV. The target photocatalyst 6Â wt% TM1-0.5Â wt% Pt-TiO2 (â
) was obtained by sensitization of Pt-loaded TiO2 with TM1. The H2 production activity of target photocatalyst â
was systematically evaluated by the reaction of photocatalytic H2 production from water under visible light irradiation. The maximum H2 evolution of 386.7 μmol in irradiation 3 h and H2 production rate of 2578 μmol · hâ1 · gâ1 was detected under the optimal conditions with pH 5, target photocatalyst â
50Â mg and 5% sacrificial reagent TEOA (v/v).
