Abstract
The successful synthesis of Ni2O3–NiCx on SnO2/glass electrodes by a combined liquid/liquid interfacial reaction and low-temperature pyrolysis process under hydrogen gas conditions, is reported. The prepared samples were analyzed by various characterization tools. To evaluate the performances of the Ni2O3–NiCx on SnO2/glass electrodes as supercapacitors, cyclic voltammetry (CV), galvanostatic charge–discharge (GCD), cycle stability and electrochemical impedance spectroscopy (EIS) were also carried out the Ni2O3–NiCx core-shell-structured electrode displayed supercapacitive behavior in 1.0 M KOH with a high specific capacitance value of 796 F g−1 and a relatively good rate capability at high current densities. Moreover, it also exhibited remarkable cycle stability, this research provides a valuable and effective approach to enhance the performance of materials applied as supercapacitors.
