The problem of global water pollution is becoming increasingly serious, especially in industrial wastewater from industries such as textiles and printing, which contains a large amount of toxic and harmful organic dyes, causing serious water pollution problems. It is urgent to remove organic dyes from wastewater and improve the quality of water resources. In wastewater treatment, adsorption is considered the most convenient, economical, and efficient method for treating dye wastewater, and can be used in large-scale production. Molybdenum disulfide nanomaterials have attracted the attention of researchers, especially in the field of wastewater treatment, due to their unique physical, chemical, electrical, biological, and mechanical properties.
