| 摘 要： | 分别以紫外杀菌灯和黑光灯为光源，研究了TiO2薄膜催化剂上甲醛的光催化氧化反应．实验结果表明，紫外杀菌灯照射下，甲醛的光催化降解率明显低于以黑光灯为光源时甲醛的光催化降解率．采用傅立叶红外光谱(FT-IR)和热分析(TG-DTA)对反应后的TiO2光催化剂进行分析和表征，对两种不同光源照射下甲醛光催化降解率的差异进行了初步探讨．

| Abstract: | The photocatalytic degradation of formaldehyde was studied on the surface of TiO2 film photocatalyst under the illumination of ultraviolet lamp and black lamp respectively. The results indicated that the conversion of formaldehyde was lower under illumination of ultraviolet lamp than that of black lamp. TiO2 photocatalysts after photocatalytic reaction were characterized by fourier transform infrared spectroscopy (FT-IR) and differential thermogravimetric (TG-DTA) analysis. The reason of difference of photocatalytic efficiency under illumination of UV lamp and black lamp was discussed. |
