| 摘 要： | 通过水热法制备了BiVO4和BiVO4/海泡石光催化剂,利用AgNO3作为前体试剂,在光照的条件下,制备了不同银负载量的Ag/BiVO4/海泡石复合光催化剂.利用XRD、SEM、TEM、XPS和DRS等测试手段对光催化剂的性质等进行了表征.以罗丹明B为模型污染物,考察了不同银负载量对Ag/BiVO4/海泡石复合光催化剂性能的影响.结果表明,当银的负载量达到60％时,复合光催化剂对罗丹明B的脱色效果最好,可在10 min之内完全将罗丹明B脱色.同时0.6 Ag/BiVO4/海泡石样品具有一定的循环稳定性,可多次使用.

| Abstract: | BiVO4 and BiVO4/sepiolite were prepared by hydrothermal method, and Ag/BiVO4/sepiolite composite photocatalysts with different Ag loadings were prepared under the light using AgNO3 as a precursor reagent. XRD, SEM, TEM, XPS and DRS were used to characterize the photocatalysts. Using rhodamine B as a model pollutant, the effects of different Ag loadings on the performance of Ag/BiVO4/sepiolite composite photocatalysts were investigated. The results show that when the loading of Ag reaches 60%, the composite photocatalyst has the best decolorization effect on rhodamine B, and the rhodamine B can be completely decolorized within 10 minutes. At the same time, the 0.6Ag/BiVO4/sepiolite sample shows substantial recyclability and cycling stability. |
