| Abstract: | A visible- light- induced photocatalyst Bi2WO6 terized by SEM. The photocatalytic activity was studied by was prepared by hydrothermal method and were charac- degrading phenol in wastewater. The results showed that the degradation rate of Bi2WO6 to phenol in wastewater can reach 95 % above, under the optimal conditions, which is pH = 1,1.00 g/L of catalyst,30 mL/min of air,3 h of illumination time, and 400 w of metal halide light. |
