摘要
本文阐述了纳米光催化剂半导体的基本原理及光催化材料体系的研究进展;并从光催化材料体系的氧化物、氮化物以及磷化物产生光生电子-空穴对的环境和抑制光生电子-空穴对的复合出发,提出了提高光催化材料性能的几种途径:过渡金属掺杂和非金属掺杂、半导体复合、表面负载、表面光敏、贵金属沉积、外场耦合等。
This thesis mainly expounds the basis principle of Nano-photocatalytic semiconduhor and the progress that has been made in the research of the photocatalytic materials system. In the system of photocatalytic material , oxide, nitride and phosphide can produce Electron-hole pair and restrain the combination of Electron-hole pair. In this situation , several ways have been put forward to improve the property of photocatalytic materials, such as transition metal and Non-metal dopring, the semiconductor complex, surface loading photosensitization, noble metal deposition and the external field coupling.
