摘要
纳米TiO_(2)化学性质稳定,光催化降解效率高、反应温和、无毒、价廉,无二次污染。阐述了光催化反应机理,介绍了光催化技术在处理汽车尾气方面的应用以及在道路施工中的应用,对使用前后NO_(x)浓度监测结果表明,纳米TiO_(2)降解氮氧化物效果明显。
Nanometer has stable chemical property,high photocatalytic degradation efficiency,mild reaction,no toxicity,low price and no secondary pollution.The mechanism of photocatalytic reaction is elaborated,and the application of photocatalytic technology in the treatment of automobile exhaust and its application in road construction are introduced.The monitoring results of NO_(x)concentration before and after use show that,the effect of nano-TiO_(2)for oxychloride degradation is obvious.
