摘要:

光催化技術是解決能源短缺和環境污染問題的最有效解決途徑之一，近期引起了世界各國科學家們的廣泛關注。然而，目前光催化材料較低的轉化效率，嚴重制約了光催化技術的進一步發展和實際應用。因此，設計和制備新型高效光催化材料具有重要意義。我們基于材料晶體結構設計，并結合材料微結構調控和制備技術，從拓展光催化材料的光吸收范圍和提高光生載流子分離效率兩個制約光催化效率的最主要問題入手，提出了一些新型高效光催化材料的設計理論和制備方法。本文主要圍繞表面等離子體光催化材料、紅外光催化材料、極性光催化材料等幾種新型光催化材料，從材料設計理論、制備方法、結構與性能之間的關系及光催化圍觀機理進行了詳細討論。

Abstract:

Photocatalysis is regarded as one of the most promising strategy to solve Energy and Environmental problems of human society, which have attracted increasing interests all over the world. However, the further development and practical applications are greatly limited owing to the low photocatalytic efficiencies. Therefore, it is the most important issue to design and synthesis new kinds of photocatalysts with high conversion efficiencies. We recently proposed some new ideas on designing and synthesis of highly reactive photocatalysts from the aspect of crystal structure design, which have been summarized in this work in details. In this work, we mainly focused and presented some information on the designing theories, synthesis methods, structure-property relationship, and photocatalytic mechanism of several new photocatalysts including plasmonic photocatalysts, Infrared photocatalysts and polar-photocatalysts.
