摘要
对热解Ｔｉ（ＯＣ４Ｈ９）４＋ＡｇＮＯ３溶胶制备的ＴｉＯ２（Ａｇ）纳米半导体薄膜光催化特性与其结构的关系进行了研究。薄膜对二卡基砜的光催化降解结果表明，热解温度显著影响薄膜的光催化作用，这与ＴｉＯ２微粒的长大和晶相转变有关；适量的Ａｇ作活性剂可以显著改善薄膜的光催化性能。
The nano metre TiO 2(Ag) thin film is prepared by the pyrolysis process from Ti(OC 4H 9) 4 and AgNO 3 solution, and their structure and photocatalysis characteristics are studied The photocatalytic degradation effect of the thin film on dibenzyl sulf one show that photocatalytic action of TiO 2(Ag) thin film is influenced by the pyrolytic temperature due to the growing particle and phase transformation Photocatalytic action would be stronger when Ag concentration properly increased (7 refs )
