| 摘 要： | 以Bi（NO3）3·5H2O、 Na2WO4·2H2O、 AgNO3为原料,利用液相沉淀法制备Bi2WO6及Ag掺杂Bi2WO6光催化剂,以亚甲基蓝溶液为目标降解物,对其降解效率进行研究。研究结果表明,当亚甲基蓝溶液的浓度为15 mg/L,体积为50 mL,降解时间3.5 h, Bi2 WO6降解率仅为55%；当Ag/Bi摩尔比为0.4%时, Ag/Bi2 WO6表现出较好的催化性能,相同时间降解率达到97%。

| Abstract: | Ag/Bi2 WO6 with highly efficient photocatalytic activity under visible light irradition were synthesized using Bi（NO3）3·5H2O, Na2WO4·2H2O, and AgNO3 as starting materials. The degradation efficiency of methylene blue was studied. The results showed that Ag/Bi2 WO6 with 0. 4% mole ratio had a higher photocatalytic activity, the 97%degradation of methylene blue （15 mg/L） was obtained after visible light irradiation for 3. 5 h. |
