摘要：

Using photocatalysts to split water into hydrogen and oxygen is a promising way to produce renewable energy. The efficient and stable photaocatalysts are desired for overall water splitting under visible light. We demonstrate the Cobalt (II) oxide (CoO)/graphitic carbon nitride (CoO/g-C₃N₄) composites synthesized by one-step thermal decomposition method exhibit enhanced photocatalytic efficiency for overall water splitting without sacrificial reagents. The 10%CoO/g-C₃N₄ exhibits optimal photocatalytic performance, where H₂ and O₂ evolution rates are respectively 0.46 μmol/h and 0.21μmol/h under visible light irradiation without any sacrificial reagents. It is worth mentioning that the H₂ and O₂ production almost approach the stoichiometric ratio 2:1. The enhanced photocatalytic activity of CoO/g-C₃N₄ may be ascribed to the efficient charge separation and fast decomposition of H₂O₂ by CoO.
