ACF担载TiO2光催化降解甲醛的影响因素研究
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 5
Abstract
采用溶胶-凝胶法(sol-gel)在活性炭纤维(ACF)表面制备了纳米TiO2薄膜光催化材料，利用XRD和SEM对薄膜进行了表征。使用该负载型纳米TiO2光催化材料处理室内空气中的甲醛污染物，分别研究了TiO2涂膜次数、甲醛初始浓度、相对湿度、温度以及光源等因素对甲醛降解效率的影响。实验结果表明，所制得的TiO2为锐钛矿型，平均粒径为20 nm左右，TiO2涂膜次数为3层时甲醛降解效率最高；甲醛初始浓度越高降解效率越低，甲醛降解效率随温度升高而增大，相对湿度为48%时甲醛降解效率最高；一定波长(λ<387 nm)的紫外光照射是使用TiO2光催薄膜降解甲醛的必要条件。
