This article presents the synthesis of CuO/rGO nanopellets using coprecipitation method, exhibiting promising performance as electrode material for supercapacitors, glucose, and H2O2 sensors. The nanopellets show specific capacitance of 188 F g-1, high capacity retention, glucose sensitivity of 0.805 mA mM-1 cm-2, and H2O2 sensitivity of 84.39 mu A mM-1 cm-2.
In the present article, graphene oxide (GO) sheets and monoclinic copper oxide (CuO) nanocrystals are connected with each other and result in the formation of CuO/rGO nanopellets, and these nanopellets synthesized using coprecipitation method. The nanopellet structured CuO/rGO composite on carbon cloth, which act as current collector exhibits specific capacitance of 188 F g-1 at a current density of 0.2 A g-1 and up to 96.3% capacity retention after 2000 charge-discharge cycles. It shows a maximum energy density of 7.32 Wh kg- 1 and power density of 53 W kg- 1. The glucose sensing characteristics of CuO/rGO nanopellet is investigated on carbon cloth and ITO substrate. It shows glucose sensitivity of 0.805 mA mM-1 cm-2 and 0.2982 mA mM-1 cm-2 for a bundle like structured CuO/rGO composite on carbon cloth and ITO substrate, respectively. Further H2O2 sensing is studied on ITO substrate, which manifests H2O2 sensitivity of 84.39 mu A mM-1 cm-2. The results indicate that nanopellet structured CuO/rGO composite could be a promising electrode material for supercapacitor, glucose, and H2O2 sensor.
