摘　　要：纳米TiO_2作为一种光催化剂,可以净化室内空气,尤其是甲醛。综述了纳米TiO_2降解甲醛的光催化机理,着重介绍了溶胶-凝胶法固化纳米TiO_2的优点、体相掺杂改性对纳米TiO_2的光催化活性的提高以及纳米TiO_2光催化降解甲醛的研究进展。通过优化光催化薄膜的制作工艺,发现更高效的体相掺杂剂扩展TiO_2光催化的光谱响应范围,是提高纳米TiO_2光催化作用、降解甲醛的有效途径。Nano-TiO2 as a photoeatalyst, can purify indoor air, especially for formaldehyde. The mechanism of nano-TiO2 photocatalytic degradion of formaldehyde is reviewed, and the advantages of solidified nano-TiO2 with sol-gel method, modification of nano-TiO2 with bulk doping to enhance the activity of nano-TiO2 photocatalysis, and the research progress of nano-TiO2 photocatalytic degradion of formaldehyde are introduced emphatically. Through the optimization of preparation of photocatalytic film, more efficient bulk doping agent to extend the spectral response range of TiO2 photocatalysis are the effective ways to enhance nano-TiO2 photocatalytic degradation of formaldehyde.
