摘要
利用水热法制备了含Bi2WO6光催化剂,并对其进行了表征。以苯酚为降解对象,考察了不同Bi2WO6的光催化性能。结果表明,pH=1,水热180℃时,制备的Bi2WO6光催化剂的活性最佳,在400 W金卤灯下光照3 h,空气流量为30 mL/min,BiWO6用量为1.00 g/L时,对苯酚的降解效果最好,降解率可达95%。
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.
