Electrochemical detection of H2O2 was investigated on a Nafion/exfoliated graphene
oxide/Co3O4 nanocomposite (Nafion/EGO/Co3O4) coated glassy carbon electrode. The
morphological characterization was examined by scanning electron microscopy, X-ray
diffraction, and electrochemical impedance spectroscopy. The modified electrode showed
well defined and stable redox couples signal in both alkaline and natural aqueous solutions
with excellent electrocatalytic activity for oxidation of hydrogen peroxide. The response of ...
