| 摘 要： | 针对室内空气中甲醛污染严重的现状，将活性炭等多孔材料的吸附、富集功能与纳米TiO2光催化降解甲醛反应相结合，得到优异的甲醛降解效果。通过改变光催化剂纳米TiO2载体、紫外光波长以及纳米TiO2浓度等影响甲醛降解效果的因素，得到吸附-光催化降解甲醛的最佳实验条件：以10 mm厚度海绵状活性炭过滤网为载体，在波长为365 nm的紫外光照射下，TiO2浓度为4％时，甲醛去除率可达93．88％。

| Abstract: | Based on a thorough investigation of serious indoor air formaldehyde pollution, in this paper the author presents that with a combination of adsorption and enrichment of porous material （ e.g.activated carbon） and photo-catalytic degradation of formaldehyde reaction, an efficient pollution control can be reached.By changing carrier of Nano TiO2 ,wavelength of UV-light and concentration of Nano-TiO2 , the experiment of adsorption-photo-catalytic degradation of formaldehyde can be best implemented in the following conditions： with 10 mm sponge-like activated carbon filter as carrier, under the 365 mmwavelength UV-light, together with the nano-TiO2 content of 4% , the formaldehyde removal rate is 93.88%. |
