Efficient electrocatalytic oxidation of p-phenylenediamine using a novel PANI/ZnO anchored bio-reduced graphene oxide nanocomposite

Herein, a novel approach was reported for the fabrication of a polyaniline/ZnO-anchored bio-reduced graphene oxide nanocomposite via in situ chemical polymerization of aniline doped with bio-reduced GO and ZnO through - interaction and electrostatic interaction. The structure elucidation was carried out using FTIR spectroscopy, XRD, and Raman and XPS spectroscopy and morphological characterizations were performed using SEM and HR-TEM. The electrochemical behaviour was investigated using cyclic voltammetry and further, electrocatalytic oxidation of p-phenylenediamine' was successfully recorded using differential pulse voltammetry.
