<p>The sugar companies produces large quantities of wastewater, referred to as spent wash, which is notable for its high levels of organic matter, pigmentation, and toxicity. This effluent presents considerable environmental difficulties. Inadequate disposal practices can result in diminished amounts of dissolved oxygen, disturbance to aquatic life, and contamination of drinking water. Conventional treatment techniques such as biological treatment, chemical oxidation, and adsorption frequently prove ineffective in breaking down the intricate organic compounds found in spent wash. Semiconductor photocatalysis, which harnesses light to produce reactive oxygen species that break down complicated organic compounds into harmless chemicals, demonstrates potential. Molybdenum disulfide (MoS₂) is a very efficient photocatalyst due to its distinctive structural, electrical, and optical characteristics. The objective of this work is to create and analyze nanoparticles based on MoS₂, specifically MoS₂/TiO₂, for the purpose of degrading spent wash by photodegradation. This will be achieved by utilizing a modified hydrothermal process. The produced nanoparticles undergo analysis utilizing X-ray diffraction, UV-Visible spectroscopy, Fourier transform infrared spectroscopy, and scanning electron microscopy. The photocatalytic efficiency is assessed by measuring the deterioration of a simulated spent wash solution under sunshine. The findings demonstrate that MoS₂/TiO₂ nanocomposites display improved photocatalytic performance, particularly with a 10% concentration of TiO₂. This concentration successfully breaks down organic contaminants in wasted wash, underscoring the nanocomposites promise for sustainable treatment of industrial wastewater.</p>
