TiO2光催化降解有機(jī)污染物研究進(jìn)展
摘要: 近年來對(duì)光催化降解有機(jī)物進(jìn)行的廣泛研究,使得非均相光催化以各種各樣的形式出現(xiàn).目前,在光催化領(lǐng)域里,TiO2起著非常重要的作用,與其它半導(dǎo)體相比,它具有成本低、惰性以及光穩(wěn)定性的特點(diǎn).本文綜述了有關(guān)在光照射下以TiO2對(duì)有機(jī)污染物催化降解情況的研究進(jìn)展,闡述了TiO2在紫外光和可見光下的光化機(jī)理,并對(duì)TiO2光催化降解有機(jī)物的研究前景進(jìn)行了展望. Abstract: Even though heterogeneous photocatalysis appeared in many forms, photodegradation of organic pollutants had recently been the most widely investigated. By far, titania had played a much larger role in this scenario compared to other semiconductor photocatalysts due to its cost effectiveness, inert nature and photostability. The research progress on the photocatalytic degradation of organic pollutants using TiO2 under of light was reviewed. The photo-catalyzed mechanism under UV and visible light was described and the outlook was made for this study. 作 者: 張鵬會(huì) 王九思 韓迪 ZHANG Peng-hui WANG Jiu-si HAN Di 作者單位: 蘭州交通大學(xué)化學(xué)與生物工程學(xué)院,甘肅,蘭州,730070 期 刊: 化工技術(shù)與開發(fā) Journal: TECHNOLOGY & DEVELOPMENT OF CHEMICAL INDUSTRY 年,卷(期): 2009, 38(7) 分類號(hào): X783 關(guān)鍵詞: TiO2 可見光 有機(jī)污染物 光催化 Keywords: titanium dioxide visible light organic pollutants photocatalysis【TiO2光催化降解有機(jī)污染物研究進(jìn)展】相關(guān)文章:
