The study demonstrates strong photocatalytic activity, degrading methylene blue by 92% using SnS2/TiO2 composites.
This thesis primarily prepared SnS2 and TiO2 monomers, and subsequently fabricated SnS2/TiO2 composites via a one-step hydrothermal method using tetrabutyl titanate, anhydrous ethanol, and concentrated nitric acid. The morphologies of the two prepared monomers and the SnS2/TiO2 composite were characterized using scanning electron microscopy (SEM). The photocatalytic performance was evaluated by degrading methylene blue solution under xenon lamp irradiation. The results demonstrate that the SnS2/TiO2 composite exhibits excellent photocatalytic activity, achieving a degradation rate as high as 92% for the methylene blue dye.
