Efficient photocatalytic degradation of industrial dyes using SnWO4 for wastewater treatment

Year: 2025

Type: article

Abstract: This work described an in-depth comparative study of photocatalytic potential of Tin Tungsten oxide that synthesized by sol-gel and hydrothermal methods for degrading dyes from water, hydrogen production , and investigating the differences in their properties by applying advanced characterizing techniques. XRD confirmed the crystal structures, SEM described their morphologies, FT-IR and UV-Vis showed the existence of SnWO 4 functional bonding and optical properties . Optical absorption capabilities, surface area , and carrier mobility effect the photocatalytic activities and water splitting. SnWO 4 -SG showed good results during water splitting and hydrogen production and SnWO 4 -SG method often yields materials with higher crystallinity and fewer defects, facilitating improved charge carrier mobility crucial for photocatalytic applications. Surface properties are also positively influenced, as sol-gel process modified surface hydroxyl groups and active sites, enhancing reactant adsorption and promoting better electron-hole separation. Over five consecutive cycles, SnWO 4 showed above 90 % efficiency of degradation.
