Charge Separation Efficiency

The Cd0.3In2S4-Zn0.7In2S4 composite photocatalyst doped with transition metal Cu2+ has been synthesized by hydrothermal method. The physical and photophysical properties of the above-prepared photocatalysts were characterized by XRD, UV-Vis, SPS, SEM and XPS. The XRD peaks of Cu2+ doped Cd0.3In2S4-Zn0.7In2S4 were almost the same as the crystal structure of Cd0.3In2S4-Zn0.7In2S4. The UV-Vis absorption edge of Cu2+ doped Cd0.3In2S4-Zn0.7In2S4 shifted monotonically to long wavelength. The photocatalytic activity of Cu2+ doped photocatalysts had been improved as a result of the enhancement of the charge separation efficiency. The results indicated that the photocatalyst of Cu2+(2wt %)-Cd0.3In2S4/Zn0.7In2S4 exhibited the highest photocatalytic activity with the rate of H2 evolution to be 1141 μmol/(h·g) under visible light irradiation.

The modification in which an Au co-catalyst is replaced with a bimetallic AuCu co-catalyst to build a TiO2-based composite photocatalyst not only enhances the interaction of the metal layer with the TiO2 substrate, but also promotes electron transfer and charge separation across the interface.
