摘要:

双金属复合氢氧化物(LDHs,又叫水滑石)因具有层状结构、稳定的物化性质和电子特性等优点,可以大范围地应用在污水处理中。目前,水滑石作为光催化剂及其复合材料在污水处理上的应用受到越来越多的关注。综述了水滑石光催化剂的制备及其改性,着重介绍了不同类型水滑石对水中不同污染物的去除效果,并简要阐述了水滑石光催化剂的作用机理和研究现状。最后,展望了水滑石光催化剂的发展趋势,以期为后续水滑石在污水处理上的应用提供借鉴。

关键词: 水滑石, 光催化, 水污染治理, 降解污染物, 水滑石改性

Abstract:

Layered double hydroxides (LDHs),also known as hydrotalcite,can be widely employed in water pollution treatment because of their special layered structures,high physicochemical stability,and electronic properties.The application of LDH composites as catalysts for photocatalysis has received increasing attention.Therefore,the preparation and modification of LDH photocatalysts were reviewed,and the removal effect of pollutants from wastewater exerted by different LDHs was emphatically introduced.In addition, the mechanism and research status of LDH photocatalysts were briefly described.Finally,the development trend of LDH photocatalysts was prospected to provide a reference for the subsequent application of LDHs in water pollution treatment.

Key words: LDHs, Photocatalysis, Water pollution treatment, Degradation of pollutants, Modification of LDHs
