TiO2/Ag3PO4复合催化剂的制备及光催化性能测试

Preparation and Photocatalytic Performance Test of TiO2/Ag3PO4 Composite Catalyst

PPCPs的广泛使用及新药的逐步引入,其代谢物不断积累,造成的水体安全问题不容忽视。本工作以钛基作为载体,设计制备了基于垂直取向纳米管阵列的TiO2/Ag3PO4复合纳米催化剂。借助XRD、SEM、UV-Vis、荧光测试等手段对制备的催化剂进行表征和分析,通过对目标污染物罗丹明B及舒必利的光催化降解实验来评估其光催化能力。研究表明该催化剂在太阳光照射下有较高的光催化活性,并且稳定性好,具有水处理实际应用的潜力。

With the widespread use of PPCPs and the gradual introduction of new drugs,its metabolites continue to accumulate,resulting in water safety issues that cannot be ignored.A TiO2/Ag3PO4 composite nanocatalyst based on a vertically oriented nanotube array was designed and prepared using titanium as a carrier.The prepared catalyst was characterized and analyzed by XRD,SEM,UV-Vis,fluorescence test,etc.The photocatalytic ability of the target pollutants RhB and sulpiride was evaluated by photocatalytic degradation experiments.Studies showed that the catalyst had high photocatalytic activity under sunlight and had good stability and high potential for practical application in water treatment.
