| 中文摘要: |
| 随着全球环境问题与能源问题的不断加剧，人们迫切需要开发一些高效、环保、稳定的光催化剂。卤氧化铋(BiOX，X=Cl、Br、I)因其独特的层状结构，优异的光学、电学性能，在光催化领域受到了越来越多的关注。虽然BiOX光催化剂在光催化反应中展现出了优异性能，但其光催化效率仍有待提高。简要叙述了BiOX的结构与性能以及当前主流的制备方法，主要概述了最近几年卤氧化铋光催化剂改性的研究进展。改性方法主要有微结构调控、晶面与缺陷调控、掺杂、构造异质结等，这些方法主要是通过提高卤氧化铋或卤氧化铋复合物的光吸收能力、光生载流子的分离和运输效率、以及活性位点的暴露量来实现改性。介绍了其在环境、能源和生物等领域的应用，同时对BiOX的发展提出了问题和展望。 |

| With the aggravation of the global environment and energy problems, people urgently need to develop some efficient, environmentally friendly and stable photocatalysts. Bismuth oxyhalide (BiOX, X=Cl, Br, I) has attracted more and more attention in the field of photocatalysis because of its unique layered structure and excellent optical and electrical properties. Although BiOX photocatalyst exhibits excellent performance in photocatalytic reaction, its photocatalytic efficiency still needs to be improved. The structure and properties of BiOX and the current mainstream methods for preparing BiOX were briefly described. The research progress in the modification of bismuth oxyhalide photocatalyst in recent years was summarized. The main modification methods included microstructure control, crystal plane and defect control, doping, structure heterojunction, etc. These methods could achieve modification by improving the light absorption capacity, the separation and transport efficiency of photogenerated carriers and the exposure of active sites of bismuth oxyhalide or bismuth oxyhalide compounds. The application in the fields of environment, energy and biology was introduced. At the same time, the problems and prospects for the development of BiOX were put forward. |
