Abstract

A nanocomposite of Zn-doped Iron oxide/Graphene Oxide/Chitosan was prepared by simple solution mixing and evaporation using ultrasonication. Formation of composite in nano-dimensions was proved by XRD, TEM and AFM studies. Electrochemical characterization of the nanocomposite has shown that the composite had good electrochemical stability. Nyquist plot has shown a well-defined semicircle indicating its good capacitance behavior. Impedance studies through Bode phase angle plot have shown nearly 90° phase angle, indicating the nanocomposite as a very good candidate for supercapacitor applications. The synthesized nanocomposite has shown photocatalytic activity in sunlight against methylene blue dye with a highly efficient removal of 97.2% in 60 minutes.
