| 摘 要： | 采用溶胶-凝胶法将纳米TiO2负载在活性碳纤维上,制备出一种新型甲醛气体清除材料。在制备中依次掺杂Fe3+和十二烷基苯磺酸钠(SDBS)对纳米TiO2进行改性,研究了纳米TiO2光催化活性的变化,并测试了自制材料的甲醛清除效率。结果表明:Fe3+和SDBS的添加不会改变纳米TiO2的晶型结构,但有利于晶粒的成长和负载膜的光催化活性;添加体积分数分别为0.8%的Fe3+和3%的SDBS时,材料的甲醛清除效率最高。

| Abstract: | A new kind of materials to remove formaldehyde gas was prepared by loading nano-TiO2 on the activated carbon fibre.In process of preparation,the sol-gel method was utilized.Nano-TiO2 was modified by adulterating Fe3+ and sodium dodecyl benzene sulfonate(SDBS).The photocataltic activity of nano-TiO2 was analyzed and the materials′removal ratio of the formaldehyde was tested.The results show that the addition of Fe3+ and SDBS cannot change the crystal structure of nano-TiO2 but improve the light-catalysed activity of nano-TiO2 and that the materials′ removal ratio of formaldehyde is highest with the addition of 0.8% Fe3+ and 3% SDBS. |
