| 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. |
