纳米TiO2因化学稳定性高、无毒、环保和成本低等优点而成为重要的光催化材料。目前室内空气污染形势严峻,严重危害人类健康,纳米TiO2光催化降解室内挥发性有机物(VOCs)活性高,具有很好的应用价值。介绍了纳米TiO2光催化治理VOCs的机理,综述了纳米TiO2的离子掺杂、共掺杂、半导体、多孔材料、石墨烯复合等改性研究及其在光催化降解VOCs中的应用研究进展,并且提出了纳米TiO2改性及其在VOCs光催化治理应用中存在的问题和进一步研究的方向。

Abstract

Nano-TiO2 has become important photocatalytic material because of its high chemical stability,non toxicity,pollution-free and low cost.At present,the situation of indoor air pollution is serious,which seriously endangers human health.The photocatalytic degradation of volatile organic compounds (VOCs) by nano-TiO2 has high activity and good application value.The mechanism of photocatalytic treatment of VOCs by nano-TiO2 was introduced.The modification of nano-TiO2,such as ion doping,co-doping,semiconductor,porous materials,graphene composite,and its application research progress in photocatalytic degradation of VOCs were reviewed.The existing problems and further research directions of nano-TiO2 modification and its application in photocatalytic treatment of VOCs were put forward.
