Study of photocatalytic asset of the ZnSnO3 synthesized by green chemistry

In this paper, we report a simple one-step mechanochemical synthesis method with a green chemistry approach for a light-induced heterogeneous oxide photocatalyst, ZnSnO3. The catalyst was characterized by various investigative techniques, like Infrared Fourier Transform Spectroscopy, Diffused Reflectance UV-visible Spectroscopy, X-ray Diffraction, Scanning Electron Microscopy, Tunnelling Electron Microscopy, and Thermogravimetric analysis to carry out structural and spectroscopic properties of the photocatalyst. The synthesized ZnSnO3 particles had an average size of 105 nm with a band gap of 3.34 eV. The photocatalyst was thermally stable over a wide range of temperatures. The sunlight mediated degradation of Methyl blue, Indigo carmine and Acid violet dyes were achieved by using ZnSnO3. (C) 2012 Production and hosting by Elsevier B.V. on behalf of King Saud University.
