摘要

Cu₂O nanoparticles (NPs) were directly formed on g-C₃N₄ via a one-pot in-situ reduction method. The physical and photophysical properties of these Cu₂O NPs modified g-C₃N₄ photocatalysts were characterized to investigate the effects of Cu₂O NPs on the photocatalytic activities of g-C₃N₄. Close contact was formed between Cu₂O and g-C₃N₄ and the Cu₂O NPs were well dispersed on g-C₃N₄. The visible light photocatalytic hydrogen production activity over g-C₃N₄ was enhanced by more than 70% with Cu₂O NPs modification. It is revealed that the efficient visible light absorption and Type II band alignment induced charge separation by Cu₂O NPs modification should be the key factors for improved photocatalytic performance.
