光催化技術是一種治理環境污染的新技術，但由于存在2個瓶頸問題（光催化活性需要紫外光激發及量子轉換效率低）而制約了其推廣應用。圍繞上述問題，國內外開展了大量的改性研究并取得了一定的成果，尤其是近年來開始重視該方面的理論研究，這對推動光催化技術的發展起到了重要作用。介紹了本課題組及文獻報道的對離子摻雜銳鈦礦相TiO2光催化材料理論研究方面取得的主要結果，總結了不同離子摻雜及共摻雜對TiO2晶體結構、電子結構、光學性質和光催化性能的影響規律，提出了如何選擇合適的摻雜離子以便有效地提高TiO2光催化性能的方法。
- Abstract:
-
Photocatalytic technology is a new method for environmental pollution control, but its application has been limited for low quantum conversion efficiency and requiring UV light to excite photocatalytic activity. To solve the problems, a large number of experimental studies have been carried out and some achievements have been obtained, especially the theoretical study developed in recent years that has attracted attentions and promoted the development of photocatalytic technology. Main theoretical results on ion doping anatase TiO 2 photocatalyst reported in literatures and by our group are reviewed. The influences of different ions doping or codoping on TiO 2 crystal structure, energy band, optical and photocatalytic properties are summarized. Methods on how to choose appropriate doping ions have been suggested for effectively improving TiO 2 photocatalytic property.
