The catalytic oxidation of organic pollutants in water and soil using layered double hydroxides and their composites: A critical review
Source abstract
Abstract
Layered double hydroxides (LDH) exhibit excellent catalytic properties for use in the field of environmental remediation due to the tunable properties, large interlayer spaces, and chemical stability. This review underscores the crucial role of LDH materials as catalysts for addressing environmental challenges caused by organic pollutants . It provided a thorough overview of the advancements in LDH materials and their composites used in catalytic oxidation, emphasizing their potential as effective agents for wastewater treatment and soil remediation. At the core of this analysis was a critical examination of LDH and their composites in heterogeneous catalysis, mainly focusing on Fenton and Fenton-like reactions, and persulfate-based advanced oxidation processes aimed at efficiently removing organic pollutants such as dyes and micro-pollutants. Furthermore, the review also explored the complex mechanisms involved in removing these contaminants, encompassing both radical-mediated and non-radical pathways (such as electrostatic interaction and singlet oxygen generation), were thoroughly analysed. Finally, the review concluded with a forward-looking perspective on future research directions.
