Abstract

Hierarchical structures consisting of highly conductive Au nanoparticles decorated on NiO nanostructures could significantly improve electrical conductivity. Herein, the Au–NiO composite exhibits greatly improved rate performance as pseudo-capacitors, and a high specific capacitance value of 619 F g−1 at a high rate of 20 A g−1, which is much higher than that of pure NiO electrodes (216 F g−1).
