A hierarchical MoO2/Au/MnO2 heterostructure was prepared by a two-step electrodeposition method. The ion-diffusion and charge-collection capacity improved after spraying a Au layer. Electrochemical tests show that the areal specific capacitance for MoO2/Au/MnO2 is up to 112 mFcm(-2) at a scan rate of 5 mVs(-1). Furthermore, the obtained MoO2/Au/MnO2 heterostructure also displays an excellent rate capability and remarkable cycling stability.
