Co1-xZnxIn2S4 Photocatalysts for Photocatalytic H2 Production Activity

[摘要] In this work, Co1-xZnxIn2S4 nanocomposites photocatalysts were synthesized by hydrothermal method, and characterized by UV-visible DRS. The prepared Co0.5Zn0.5In2S4 nanocomposites, which exhibits the highest H2 production rate, the value is 36.08 umol•h-1•g-1, exceeding more than 8 times compared with the pure ZnIn2S4 and CoIn2S4. Co0.5Zn0.5In2S4 nanocomposites also has good reuse and stability. Two reasons lead to higher photocatalytic H2 production activity are enough visible-light absorption capacity and suitable conduction band potential of the Co0.5Zn0.5In2S4. In this research, it is proven that Co0.5Zn0.5In2S4nanocompositesphotocatalystscan enhance the photocatalytic H2 production activity. The significant improvement in the performance of Co0.5Zn0.5In2S4 nanocomposites is mainly due to effective charge separation.
