| 摘 要： | 用纳米TiO2作为光催化剂覆膜于工业中普遍使用的PTFE滤料，得到了一种新型滤料。设计搭建了仿真空气净化系统的光催化实验台，分析了初始浓度、净化风速、紫外光强度、温度和相对湿度对甲醛光催化降解效率的影响。实验结果发现，在实验区间内，降解效率随初始浓度和紫外光强度的增加而提高；净化风速和温度对降解效率有双重影响；低的相对湿度对应了较高的降解效率。

| Abstract: | Polytetrafluoroethylene filter,a low cost and commonly used material in industry,is successfully employed as the substrate for nano TiO2 photocatalyst coating at room temperature.A specific experimental set-up that is similar to actual air purification system is developed for the testing.The effects of initial concentration,reaction temperature,light source intensity and realtive humidity on formaldehyde photocatalytic degradation rate of some key factors are investigated.Experiments show that within the ex... |
