The effects of C3N4, CTAB, AgBr concentrations and hydro-thermal temperature on the photocatalytic activity of ZnO composite photocatalysts towards sun-light driven degradation of methyl orange have been investigated. The structural, characteristic analysis and photo-catalytic properties of the ZnO composite photocatalyst were studied by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), Brunauer-Emmett-Teller (BET) and UV–visible absorption spectroscopy.
The results show that the addition of 3% C3N4, 43% AgBr, 0.03M CTAB in ZnO, and the hydrothermal temperature of 160°C with a hydrothermal time for 30 mins in AgBr/C3N4/ZnO composite photocatalyst possesses the best photocatalytic performance. The C3N4/ZnO photocatalytic of methyl orange degradation efficiency reaches to 96% under UV light, and the AgBr/C3N4/ZnO photocatalyst reaches to 79% under visible light. Thus, this study has demonstrated that the modification of ZnO by AgBr and C3N4 can enhance the photocatalytic activity.
