环境安全中光催化技术的应用

针对近年来环境安全的研究现状,提出以非传统安全的视角研究环境安全的问题,运用纳米光催化技术取得的最新科研成果解决环境安全问题的新思路。综述了纳米科技在环境安全中的应用,重点评述纳米光催化技术在室内空气净化中的应用(如光催化降解有机污染物、无机污染物、氮氧化物、异味、微生物)和利用纳米光催化技术在室内空气净化中取得的最新科研成果(如抗菌防霉内墙材料、防污自洁材料、自动无毒化材料)。同时指出纳米二氧化钛光催化技术尚未完全达到实际应用水平,仍存在一些明显的不足之处,需要对该技术继续开发和完善,才能在环境安全领域获得更加广泛和有效的应用。

Applications of Photocatalytic Technology to Environmental Safety

According to the recent research status of environmental safety,new research idea of researching the environmental safety problems with non-traditional perspectives and applying the latest achievements in scientific research of nanometer photocatalytic technology to solve environmental safety is put forward.The applications of nanometer photocatalytic technology to environmental safety are reviewed.Emphasis is put on the applications of nanoparticle photocatalytic technology in the interior air purge(such as degradation of organic pollutants,inorganic pollutants,nitrogen oxides,peculiar smell and microorganism) and the latest achievements in scientific research of nanometer photocatalytic technology(such as antibacterial and antifungal material,anti-fouling and self-cleaning material and automatic non-toxic material).It is pointed out that the technology of using nano-titania as photocatalyst has some obvious disadvantages and has not yet been well applied to the actual treatment process of environmental safety.Therefore,it will not be widely and effectively used until it is improved and perfected.
