摘要
本文介绍了纳米TiO2降解室内空气污染物的原理,理论分析纳米TiO2颗粒大小对其光催化氧化能力的影响程度。实验证实了纳米TiO2能有效地分解室内空气污染物。得出了空气流速、污染物浓度、紫外光强度与光催化氧化效果之间的变化关系。最后指出了纳米TiO2光催化技术发展应该注意的问题。
The principle of decompounding the indoor air pollutant by using Nano-TiO2 photochemical catalysis is introduced, and the influences of granule size of Nano-TiO2 on the ability of photochemical catalysis are analyzed. The experiment indicates that the Nano-TiO2 can decompound the air pollutant effectively and the mutative relations are concluded between the photochemical catalysis effect and the velocity of air flow, the pollutant density and the ultraviolet ray intensity. Finally the questions which should pay attention to the development of the Nano-TiO2 photochemical catalysis technology are pointed out.
