| 摘 要： | 较低的光量子效率是限制TiO2光催化技术实用化的主要原因,对其改性是提高TiO2光量子效率的重要手段。介绍了采用掺杂过渡金属、表面光敏化、表面螯合及衍生、贵金属沉积、复合半导体和添加电子捕获剂等方法对TiO2光催化剂进行改性,并对这些方面研究所取得的进展进行了简单的评述。

| Abstract: | Low quantum yield was the main restriction aspect of TiO_2 photocatalysis technology for engineering-scale applications.Modification of TiO_2 can improve its performance effectively.Based on the photocatalytic mechanism of TiO_2, some modification methods including transition metel ion-doping,composite semiconductors,dye sensitization, surface reductive treatment and surface chealation,noble metal deposition, adding electron capture agent were reviewed. |
