Research on the Preparation of (CuAg)_xIn_2xZn_2(1-2x)S2 Solid Solution Photocatalysts
ZnS-CuInS2-AgInS22solid solution photocatalysts were successfully prepared by co-precipitation method with heat treatment under different atmosphere (N2 and H2S). XRD, XRF, UV-vis, and SEM were used to characterize the prepared photocatalysts, indicated that the composition of result photocatalysts were different from each other and also the rate of charge, though they possessed a wurtzite-type phase structure. The photocatalysts all showed photocatalytic activities for H2 evolution from aqueous solutions containing SO32- and S2- as sacrificial reagents under visible light irradiation with Ru loading, but sample treated under H2S atmosphere performed better, the possible reason was proposed.
