Glucose-Reduced MnO₂/Graphene Composites Electrode for Supercapacitor

Abstract:

Green composites of Glucose-reduced graphene oxide (GrGO) and manganese (IV) oxide (MnO₂) were prepared in a typical chemical synthesis route assisted with ultrasonic irradiation. Conductivity studies conducted via 2-point probe method shows GrGO/MnO₂ (4:1) possessed electrical conductivity of 30.29 S cm^-1 with energy band gap of 8.47×10^-1 eV. The increase of D/G intensity ratio of GrGO with increase MnO₂ loading indicates more disorder carbon or defects are introduced from the reaction of carbon with MnO₄^-.
