摘要
采用硬脂酸法制备了一种新型的Cu-Sn-TiO2三元复合光催化剂,并采用XRD研究了复合催化剂的物相,且以苯酚为目标降解物对其光催化活性进行了评价。结果表明,经500℃焙烧的Cu-Sn-TiO2催化剂的晶型为锐钛矿型,并具有较高的光催化活性,以摩尔比n(Cu)∶n(Sn)∶n(Ti)=0.25∶5∶100为最佳,光催化反应3 h时苯酚的降解率达97.1%。
One novel Cu-Sn-TiO2 composite photocatalyst was prepared by stearic acid method,the crystalline phases of the samples was analyzed by X-ray diffraction. The photocatalytic activities of the samples were examined by the degradation of phenol. The results show that Cu-Sn- TiO2 composite photocatalysts possess a good photocatalytic activity, when the n（Cu） ： n（Sn） ： n（Ti） was 0.25 ： 5 ： 100, the degradation rate of phenol reached 97.1% under the following experimental conditions of solution pH：4, catalyst amount 0.5 g/L, initial phenol concentration 20 mg/L and reaction time 3.0 h.
