Design of Cu-Cu 2 O/g-C 3 N 4 nanocomponent photocatalysts for hydrogen evolution under visible light irradiation using water-soluble Erythrosin B dye sensitization

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 dye was added into...
