摘要: 用常压气相沉积法镀出的二氧化钛薄膜为光催化剂,以紫外灯为光源,降解甲基橙稀水溶液. 实验表明:镀膜时基片种类、沉积温度、在染料溶液中加Fe3+和H2O2、光照时间及气体体积流速均对甲基橙的降解率有影响,并且找到了最佳的镀膜条件.

关键词: 甲基橙, 二氧化钛薄膜, 光催化降解

Abstract: The photocatalytic degradation of methyl orange under UV-ray with titanium dioxide thin films was investigated in this work. The effects of substrate, air bubbling flow, adding Fe3+ and H2O2 in methyl orange solution were examined. Fairly good coating conditions for the photocatalytic degradation of methyl orange in aqueous solution were suggested.

Key words: methyl orange, TiO2 thin film, photocatalytic degradation
