MnMoO4•4H2O nanoplates grown on a Ni foam substrate for excellent electrochemical properties

MnMoO4 center dot 4H(2)O nanoplates (NPs) grown directly on Ni foam were synthesized by a facile hydrothermal process. As-grown MnMoO4 center dot 4H(2)O NPs directly supported on Ni foam as integrated electrodes for electrochemical capacitors demonstrated prominent electrochemical performances with a high specific capacitance of 1.15 F cm(-2) (2300 F g(-1)) at a current density of 4 mA cm(-2) and a good cycling ability (92% of the initial specific capacitance remained after 3000 cycles). The superior electrochemical performances could be ascribed to the porous structure of interconnected MnMoO4 center dot 4H(2)O NPs directly grown on current collectors, which improves electrolyte diffusion efficiency and increases electron transport. These MnMoO4 center dot 4H(2)O NPs on Ni foam with remarkable electrochemical properties could be considered as a prospective electrode material for the application of supercapacitors.
