Recent advances and perspectives of molybdenum disulfide and molybdenum disulfide based nanocomposites for adsorption and photocatalytic degradation of organic dyes: a review

Environmental contamination is a major global concern. Organic dyes pose a significant threat as water pollutants, leading to the depletion of natural resources. Molybdenum disulfide (MoS₂), a type of two-dimensional transition metal dichalcogenide, has gained considerable attention due to its impressive properties, such as stability, surface area, and tunable interlayer spacing. It has emerged as a promising material for both photocatalytic degradation and adsorption of harmful organic dyes. This article provides an overview of recent advancements in MoS₂-based nanomaterials for the removal of organic dyes from solutions through adsorption and photocatalytic processes. The review delves into the fundamental properties of MoS₂, explores various synthesis methods, and various modifications of the material to enhance its dye removal efficiency, and addresses potential challenges associated with its application in this field. Furthermore, the article discusses the prospects for improving MoS₂-based materials for enhanced adsorption and photocatalytic degradation of organic dyes.
