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[1][A. Fujishima, 1972] 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.
