Annotation

Mixed vanadium (IV and V) oxides/reduced graphene oxide (VO2/rGO and V2O5/rGO) composite was synthesized by a green method. The green method prevents the use of hazardous chemicals, viz., hydrazine hydrate, which is commonly utilized for reducing the oxygen functionalities of graphene oxide (GO). The reduction of GO and incorporation of VO2 and V2O5 were performed simultaneously in a single concerted step using Centella asiatica extract. The composite was then characterized using UV-visible spectroscopy, X-ray Diffraction (XRD), Raman spectroscopy and scanning electron microscopy (SEM). This work shows the potential of Centella asiatica extract as a reducing agent.
