Cu-Cu2O nanoparticles (NPs) decorated porous graphitic carbon nitride (g-C3N4) (Cu-Cu2O/g-C3N4) photocatalysts were prepared. When investment of copper source materials in the experiment increased to 7 wt%, the highest H2 evolution rate (400 μmol g−1 h−1) was obtained under visible light irradiation in triethanolamine solution. This is about triple of pure g-C3N4 (140 μmol g−1 h−1). Moreover, various amount of ERYTHROSIN B (cas 16423-68-0) dye was added into Cu-Cu2O/g-C3N4 photoreaction solution and a significant enhancement of H2 production rate was achieved. The highest H2 production rate was 5000 μmol g−1 h−1 with 5 mg Erythrosin B in photoreaction system. Erythrosin B dye sensitized Cu-Cu2O/g-C3N4 presented stable photocatalytic H2 evolution ability and no noticeable degradation or change of photocatalyst were detected after six recycles. A possible photocatalytic mechanism of Erythrosin B dye sensitized Cu-Cu2O/g-C3N4 for the enhancement of photocatalytic H2 evolution is proposed.
