Hydrothermal synthesis of Zn2SnO4/ZnO composite for the degradation of organic pollutant Methylene Blue under UV irradiation

In this work, Zn2SnO4/ZnO composite was synthesized by hydrothermal method with the support of Na2CO3 mineralizer. Structure, morphology and optical properties of the synthesized composite was analysed using characterization techniques such as powder x-ray diffraction (PXRD), Raman spectroscopy, UV–visible diffuse reflectance spectroscopy (UV–Vis. DRS) and Scanning electron microscopy (SEM). SEM micrographs shown distinct morphology of Zn2SnO4 in polygonal shape and ZnO particles in tetragonal morphology. The applicability of this prepared composite as a photocatalyst was tested for photodegradation of organic pollutant Methylene Blue (MB) dye. The study shown 91.5% degradation of MB dye in 120 min under UV irradiation, this indicates that Zn2SnO4/ZnO composite as an effective photocatalyst.
