Abstract

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.
