Abstract:

As an advanced oxidation technology, photocatalytic oxidation has broad application prospects in organic matter removal and water quality improvement. The light source is the limiting factor for the application of photocatalytic oxidation technology. Catalytic oxidation based on visible light is an important direction for the development of photocatalytic technology. Conventional photocatalytic materials have some defects such as low visible light utilization rate, easy recombination of photogenerated electron holes, and large energy consumption in the photocatalytic reaction. In this paper, the modification of conventional photocatalytic materials driven by visible light are reviewed and their applications in the field of water treatment are prospected.

Key words: photocatalytic material, visible light, modification, organic pollutant

摘要:

作为一种高级氧化技术,光催化氧化在有机物降解、水质改善等方面具有广阔的应用前景。光源是光催化技术应用的限制性因素,基于可见光的催化氧化是光催化技术发展的重要方向。针对光催化反应中存在的可见光利用率低、光生电子空穴易于复合、能量消耗大等不足,通过对催化材料的改性可提升催化体系在可见光驱动下的光催化效率。综述了基于可见光驱动的光催化材料的改性措施及应用,展望了可见光驱动的光催化技术在水处理领域的研究方向。
