摘要
采用溶胶-凝胶法制备了Pr-TiO2纳米复合催化剂,并用DRS、FT-IR、XRD和SEM等对样品形态和结构进行了表征,以罗丹明B(Rh B)印染废水作为探针反应,分别在紫外光和可见光照射下评价其光催化性能.与TiO2纳米催化剂的光催化活性进行对比,Pr-TiO2纳米复合催化剂对罗丹明B溶液(5 mg/L)具有较高的光催化降解性能,可见光下的降解率达到97%.
Nanocomposite catalyst of Pr-TiO2 was prepared by sol-gel method, whose morphology and structure were characterized by DRS, FT-IR, XRD and SEM. The photocatalytic activities of Pr-TiO2 nanocom?posites were investigated for the degradation of Rhodamine B (RhB) as a probe dye under the il umination of UV and visible light, respectively. Compared with the photocatalytic activity of TiO2 nanocatalyst, Pr-TiO2 showed higher photodegradation to photodegradation RhB (5 mg/L), and the degradation rate could reach 97%under sunlight radiation.
