光催化降解甲苯的研究

Study on the Photocatalytic Degradation of Toluene

本文以TiO2粉末作为光催化剂，研究光降解甲苯的可行性．结果表明，375W中压汞灯照射40min，甲苯被完全光催化降解．同时还研究了光催化剂TiO2的用量，外加H2O2、Cu2、Na离子等因素对甲苯光催化降解的影响，并从反应机理的角度给予解释。

The feasibility of photocatalytic degradation of toluene using TiO2 powders as a photocatalyst was studied.The results showed that toluene can be completely photocatalytically degraded after 40min illumination with a 375W medium pressure mercury lamp.The effect of amount of TiO2,concentrations of H2O2. Cu2+ and Na+ on the photocatalytic degradation were also investigated.The explanations were given from the reaction mechanisms.
