Abstract: The pollution of endocrine disruptor bisphenol A has become increasingly serious,resulting in big nega-tive influences on human health and aquatic organism. Photocatalytic oxidation is commonly used for the purification of wastewater. As one of the mostly studied and promising photocatalysts,TiO2 can not be widely used because of its wide band gap and large electron hole recombination rate. Therefore,attention has extensively been paid to the modi-fication of TiO2 photocatalysts. The research progress in photocatalytic degradation of bisphenol A by modified TiO2 in recent years is introduced,and the future research directions of modified TiO2 photocatalyst are proposed.

Key words: bisphenol A, modified TiO2, photocatalyst, endocrine disruptor, wastewater purification

摘要: 内分泌干扰物双酚A的污染日益严重,对人体健康和水生生物产生很大负面影响。光催化氧化法是废水净化常用的一种高级氧化技术。TiO2是研究最多、最具潜力的光催化剂之一,但其带隙较宽、电子-空穴复合率较大而无法大规模应用,因此对TiO2光催化剂进行改性得到广泛关注。介绍了近年来改性TiO2光催化剂降解双酚A的研究进展,并提出改性TiO2光催化剂今后的研究方向。
