Utilization of LDH-based materials as potential adsorbents and photocatalysts for the decontamination of dyes wastewater: a review

Abstract

Dye as a colored organic pollution has caused tremendous environmental problems. Removing dyes from effluents is of significant importance. Layered double hydroxides (LDHs), known as hydrotalcite-like compounds or ionic lamellar compounds, have attracted considerable attention recently due to the presence of large interlayer spaces, positively charged layers and solvation molecules. LDH-based materials are frequently used for environmental remediation especially for the elimination of dye compounds. This review compiles an extensive list of LDH-based low-cost sorbents and photocatalytic catalysts for dyes from the vast literature. Furthermore, performance, key factors and mechanisms involved in the processes are also included. Lastly, some major challenges together with prospects in this research field are discussed and highlighted. In conclusion, the application of LDH-based materials in the area of adsorption and catalysis science represents a useful and viable method, resulting in the outstanding capabilities in the removal of dyes from aqueous systems.
