摘要：利用自制的P t/T iO2催化剂对苯气体进行光催化降解,实验结果表明,苯的降解率最终可达100%.同时对苯的起始浓度、水蒸气含量、紫外灯光强等反应条件进行了研究,确定了最佳反应条件.此外,还对该反应的动力学和反应机理进行了探讨.
Photocatalytic degradation of benzene in humidified air streams at ambient temperature was conducted by using UV-irradiated platinized titania （Pt/TiO2） photocatalyst. The results proved possible to obtain complete overall conversion of benzene. Meanwhile, the impacts of reaction conditions, such as the initial concentration of benzene,the relative humidity and the light intensity on photocatalytic degradation of benzene were investigated. In addition,the reaction kinetics and mechanisms of benzene＇s photocatalytic degradation were also investigated.
