摘要: We report the direct splitting of pure water by light-excited graphitic carbon nitride (g-C3N4) modified with Pt, PtOx, and CoOx as redox cocatalysts, while g-C3N4 is virtually inactive for overall photocatalysis. The novelty in selective creation both H2 O2 cocatalysts on surface active sites g-C3N4via photodeposition triggering simultaneous evolution gases a stoichiometric ratio 2 : 1, irradiated light, without using any sacrificial reagents. photocatalyst was stable 510 hours reaction.
