Photocatalytic Performance of Indigo‐Dye‐Doped Graphene‐Supported BiVO4 Nanocomposite under Visible Light

Abstract In this work, novel graphene supported BiVO 4 based nanocomposites were derived successfully by employing hydrothermal method. Pure bismuth vanadate limits a number of applications because of its insufficient photo catalytic activity in ordinary sun light. So, Indigo‐Reduced graphene oxide (RGO)/BiVO 4 nanocomposites were designed as a next step to achieve efficient photo‐catalytic activity in visible light in relation to pure BiVO 4 or its other nanocomposites. Characterization of nanocomposites was carried out by X‐ray diffraction (XRD), Scanning electron microscopy (SEM) and UV–Vis spectroscopy (UV). The enhancement of the photo‐catalytic activities of the prepared nanocomposite were contributed to the effective charge transfer of photo‐generated electron from BiVO 4 to RGO and pi to pi* stacking improved absorption performance.
