摘要
采用微波辅助化学还原法制备Ag/TiO_2纳米片异质结薄膜光催化剂,通过XRD、SEM、UV-Vis、PL和光电流响应对其进行表征,并考察了其清除气相中氮氧化物(NOx)的性能。结果表明,Ag/TiO_2 NSF光催化剂对光的吸收利用好,光生载流子复合几率小,其光催化清除NO_x的活性比TiO_2 NSF高,其中1.0 Ag/TiO_2NSF的效果最好。
Heterostructured Ag/TiO2 nano-sheet film photocatalyst was prepared by chemical reduction method with microwave heating. The products were characterized by means of XRD, SEM, UV-Vis, PL, and transient photocurrent response, and their photocatalytic NOx removal performance was investigated. The results showed that the prepared Ag/TiO2 NSF had good absorption and utilization of light, and small recombination rate of charge carriers;Ag/TiO2 NSF had higher photocatalytic activity of NOx removal than that of TiO2 NSF, and 1.0 Ag/TiO2 NSF had the best performance.
