Due to the toxic effect of Methylene blue (MB) dye, its removal from water and water waste has gained significant attention in concern with green environment. In present work, a simple and low cost hydrothermal method has been used for the synthesis of copper zinc tin sulfide (CZTS) nanoparticles. Structural, morphological and optical properties of CZTS nanoparticles were characterized and it reveals that the synthesized powder has kesterite crystal structure with agglomerated morphology and shows a band gap of 1.53 eV leading to good potential to degrade methylene blue dye. When CZTS was introduced in aqueous MB solution as a catalyst and exposed to visible light for 45 min, about 50% degradation of MB was observed.
