摘　　要：纳米二氧化钛作为一种重要的光催化剂,在降解污染物方面得到了广泛应用。由于对二氧化钛进行改性可以有效地提高其光催化活性,使得对其改性也成为研究的热点。本文系统地阐述了纳米二氧化钛的光催化反应机理,光催化活性的影响因素,掺杂改性方法,研究了它在水处理中的应用现状,总结了改性过程中存在的问题,并提出了今后的研究方向。Nanoscale titanium dioxide as an important phstocatalyzer has been widely used in treatment of undegradable pollutants. The photocatalysis activity of nanoscale titanium dioxide could be improved effectively after modification, so the modified technology has become hot spot of study. This paper illustrates photocatalysis reaction mechanism, influential factors, modifying methods of nanoscale titanium dioxide and its status quo applying in water treatment fields, then summarizes the problems existing in the process and puts forward the direction of future research.
