Abstract: Water contamination caused by textile and industrial dyes is currently among the most important issues facing humanity that require urgent attention. Organic pollutants are harmful and can cause cancer in both humans and aquatic life. Even small amounts of these pollutants in water can lead to grave health problems. One promising way to clean up these pollutants is through degradation, using oxysulfide-based photocatalysts. These materials are effective because of their advanced optical and structural properties. The Sn-Mo(O,S) 3 catalysts were prepared through an easy precipitation process conducted at low temperatures. Different techniques were used to examine the catalyst's shape, structure, electrical properties, chemical makeup, and how it interacts with light. The Sn-Mo(O,S) 3 oxy-sulfide nanoparticle was successfully used to break down organic pollutants through photocatalytic processes. Among the samples made, the SMOS-25 catalyst showed the best performance in breaking down methylene blue dye. The effectiveness of the SMOS-25 catalyst was tested by seeing how well they could break down organic dye pollutant when exposed to visible light. The SMOS-25 nanoparticle was able to remove 98.9 % MB dye from water within 105 min under visible light. In this system, the main substance responsible for breaking down the dye is hydroxyl radical ( • OH).
