摘要
利用TiO2光催化氧化技术对SO2、NH3、CO、NOx进行净化研究,结果表明,TiO2光催化剂能有效降解上述四种气体,SO2、NH3、NOx、CO分别减少:73．2％、86．1％、81．4％、69．1％。并对四种气体的氧化降解进行了比较,发现催化剂失活主要是由生成的产物吸附在催化剂表面所致。
The photocatalytic oxidation using TiO2/UV was conducted, and it was found that the degradation of SO2, NH3, CO, NOx in air were all effective, reaching 73.2%, 86.1%, 81.4%, 69.1% in the ranges of experimental concentration, separately. Compared the photodegradation of four kinds of gas, the results showed that the primary factor of causing catalyst deactivation was the reaction products absorbed on catalyst surface.
