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. (C) 2021 Elsevier Ltd. All rights reserved.
