| 摘 要： | TiO2具有无毒、化学性能稳定、价格便宜和不产生二次污染等特点,被认为是最有应用前景的光催化剂.但TiO2的吸收光谱在紫外光区,对太阳光的利用率低,影响了TiO2光催化技术的推广应用.对TiO2进行改性提高它在可见光区的光催化活性是近几年研究的热点.综述了近年来利用非金属如N、F、S、C等对TiO2进行改性的研究,对改性方法进行了比较,并评价了各种离子改性的效果.

| Abstract: | At present,photocatalyst TiO_2 is considered the most application prospect because of its nontoxicity,chemical stability,inexpensiveness and non-secondary pollution.It's the research hotspot that modifying TiO_2 in order to improve its photocatalytic activity and absorbability in visible light irradiation.The recent progress in research on TiO_2 modification by doping nonmetal including N,F,S,C etc.was reviewed and summarized.Moreover,the preparation methods of doped-TiO_2 were compared,and the results of doping different nonmetals were assessed. |
