摘要
采用水热法制备分层次结构F-TiO_2微粒,并通过原位沉淀方法对这些微粒进行Ag_3PO_4负载以增强其可见光响应,研究F-TiO_2微粒的可见光催化性能(光降解罗丹明B溶液的速率),并研究了复合物中Ag_3PO_4的加入量对光催化活性的影响。结果表明,F-TiO_2微粒的光催化活性在负载Ag_3PO_4以后显著高于纯Ag_3PO_4的活性,当Ag_3PO_4与F-TiO_2的质量比为1∶1.67时,其可见光催化活性最佳。
The hierarchical structural F-TiO_2 particles are prepared by adopting the hydrothermal method,and through the in situ precipitation method,these particles are loaded with Ag_3PO_4 to enhance their visible light response for the study of their visible photocatalytic properties(speed rate of photo-degradation of Rhodamine B solution).The results show that the photocatalytic activity of F-TiO_2 particles after loaded with Ag_3PO_4 is significantly higher than that of pure Ag_3PO_4.When the mass ratio of Ag_3PO_4 to F-TiO_2 is 1:1.67,the photocatalytic activity of the visible light is the best.
