光催化涂层净化室内VOCs研究进展

Advances in Photocatalytic Coating for indoor VOCs Purification

摘要:

近年来，室内空气污染问题逐渐成为人们关注的焦点，挥发性有机物（VOCs）是造成这一问题的主要来源。光催化涂层作为一种新型VOCs净化技术，可以在太阳光下自发将VOCs降解为水和CO2，高效节能，不会产生二次污染，引起研究者的广泛关注和深入研究。结合国内外研究现状，该文系统介绍了用于室内VOCs净化的光催化涂层的制备方法以及涂层光催化性能和稳定性的影响因素，并对VOCs的光催化净化机理和影响因素进行阐述，同时对不同光催化涂层种类的研究进展及应用现状进行介绍，最后对光催化涂层进行了总结和并对其未来的发展方向进行展望。

Abstract:

In recent years, indoor air pollution has gradually aroused people's wide concern, and volatile organic compounds (VOCs) are the main source of this problem. Photocatalytic coating, as a novel VOCs purification technique, could degrade VOCs into water and CO2 under sunlight spontaneously, which is efficient and energy-saving, and will not produce secondary pollution. So it has attracted extensive attention and in-depth research by researchers so far. Based on the present status quo, this paper introduces systematically the preparation methods of photocatalytic coating and influence factors on the photocatalytic capacity and stability of coating for indoor VOCs purification. Then, different photocatalytic coatings are presented and analyzed according to available literatures. In the end, future developments and researches about photocatalytic coating are summarized and proposed.
