文摘 全球面临的能源危机和环境污染问题日益严峻,光催化技术的快速发展让人们看到了曙光,而光催化材料作为其基本要素则成了关注重点。本文主要从光催化降解水体有机污染物方面,综述了光催化技术的发展现状,9类光催化材料体系及其属性、作用机理与研究应用,以及对材料体系修饰改性的方法。最后,提出了现阶段材料体系依旧存在太阳能利用率低、量子产率低和光化学稳定性不足的问题,而金属有机骨架(MOF)新型材料体系和微纳米介孔、多级孔复合、Z型复合半导体等修饰改性方法为光催化材料体系的开发探索提供更广阔的空间。
其他语种文摘 The energy crisis and environmental pollution problem is increasingly serious on a global scale,however the rapid development of photocatalytic technology brings the dawn to solve the problem, and the photocatalytic materials system as a basic element has become the focus.The photocatalytic degradation of organic pollutants in water was focused in this article,and the development status of photocatalytic technology,nine types of photocatalytic materials and their properties,mechanism of action and the application of research,as well as modification methods of the materials were summarized. Finally,it was proposed that the materials still has the problems of low solar energy utilization, low quantum yield,and insufficient photochemical stability at the current stage,nevertheless the new material system of metal-organic framework(MOF)and the modification methods of micro/nano mesoporous, multi-hole composite,Z-scheme semiconductors provide a broader space for the exploration of photocatalytic materials.
