摘　　要：利用水热法制备了BiVO4粉体,并通过XRD、DRS等对催化剂进行了表征。以氙灯(可见光)为光源,以制备的BiVO4为催化剂进行了光催化降解水中苯酚的试验研究,并考察了H2O2的协同作用对光催化氧化的影响。试验结果表明,以500W氙灯光源照射,在pH为2.5,H2O2浓度为0.1mmol/L的试验条件下,初始质量浓度为10mg/L的苯酚废水经150min光催化反应后,其去除率可达60%。The BiVO4 catalyst was prepared by hydrothermal method and was characterized by XRD and DRS. The photocatalytic activity of the catalyst toward degradation phenol in water was studied under visible-light irradiation. The influence of the synergistic effect of H202 on photocatalysis oxidation are investigated. It was found that adding H2O2 can improve the efficiency of photocatalysis. The degradation rate of phenol was 60 % after being treated for 150 min under visible-light irradiation with BiVO4 dosage of I g/L, pH of 2.5, and H202 dosage of 0.1 mol/L.
