Enhancement of Photocatalytic activity of γ- Bi2MoO6 with Graphite flake under Visible light irradiation

The influences of the various preparation parameters (including the pH value, reaction temperature, and holding time) on the phase formation and morphology development were investigated in detail. Graphite was observed on the surface of γBi2MoO6 after the co-precipitation and calcination treatment. The synthesized Bi2MoO6 –Graphite flake composite nanoparticles (NP’s) were characterized with X-ray diffraction (XRD) for identify crystalline phases and particle size, Raman spectroscopy is identify active species during the reaction, UV-Visible diffuse reflectance spectroscopy (UV-DRS) revealed for band energy of semiconductors, Field emission scanning electron microscopy(FE-SEM) to determine morphology and shape of supported particles and Energy dispersive X-ray analysis (EDX) for elemental analysis of synthesized nanoparticles. The photocatalytic activity of Bi2MoO6 catalyst was evaluated using the degradation of Methylene blue under Visible light irradiation at room temperature. A remarkable enhancement in the visible photo light activity was observed over the Bi2MoO6-Graphite composite compared to pure Bi2MoO6.
