title: Comprehending the effect of MMoO4 (M = Co, Ni) nanoflakes on improving the electrochemical performance of NiO electrodes.
abstract: The design and fabrication of high performance supercapacitors with a high specific capacitance and a long lifespan still remain a challenge. We present two hydrothermal and two annealing processes for the fabrication of hierarchical heterostructures of NiO@MMoO4 (M = Co, Ni) nanosheet arrays on Ni foam. In this hierarchical structure, numerous MMoO4 nanoflakes grow on a NiO nanosheet and the integration of MMoO4 can improve the whole electrode's conductivity, leading to an ideal pathway for electron and ion transport. The hierarchical NiO@MMoO4 (M = Co, Ni) heterostructure electrode demonstrated remarkable electrochemical performance with a high specific capacitance and predominant cycling stability, making it one of the prospective electrode materials for high performance supercapacitors.
