采用原位水解的方法制备得到Cu2O/TiO2复合光催化材料。利用扫描电子显微镜对该复合物的形貌进行表征,研究了该复合物在可见光和紫外光下对2,4-二氯酚的光催化降解性能,和单一的Cu2O的光催化活性进行对比。研究表明,可见光下,Cu2O/TiO28h对2,4-二氯酚的降解效率可以达到92.37%;紫外光下,Cu2O/TiO23h对2,4-二氯酚的降解效率可以达到68.6%,其光催化活性优于单一的Cu2O纳米颗粒。
Cu2O / TiO2 composite photocatalyst was prepared by in-situ hydrolysis. The morphology of the composite was characterized by scanning electron microscopy. The photocatalytic degradation of 2,4-dichlorophenol under visible light and ultraviolet light was compared with the photocatalytic activity of Cu2O alone. The results show that under the visible light, the degradation efficiency of 2,4-dichlorophenol can reach 92.37% under Cu2O / TiO28h; the degradation efficiency of 2,4-dichlorophenol under Cu2O / TiO23h can reach 68.6% The catalytic activity is better than single Cu2O nanoparticles.
