Visible Light Induced Photocatalytic Degradation of Methylene Blue using Polyaniline Modified Molybdenum Trioxide

Abstract

International audiencePolyaniline/Molybdenum trioxide composite was prepared by a chemical oxidative polymerization method. The obtained Polyaniline/Molybdenum trioxide composite was characterized by X-ray diffraction analysis (XRD), Fourier transform infrared (FT-IR) spectroscopy and transmission electron microscopy (TEM). The XRD pattern showed the diffraction peaks to be in good agreement with the structure of MoO3. The obtained results confirm the successful formation of the Polyaniline/Molybdenum trioxide composite. Finally, the composite was employed as photocatalyst for the photodegradation of methylene blue under visible light irradiation. Further the photodegradation mechanism also discussed in detail
