MnMoO4·4H2O nanoplates were grown directly on a Ni foam by a facile hydrothermal route with enhanced electrochemical performances, i.e., a high specific capacitance of 1.15 F cm−2 (2300 F g−1) at 4 mA cm−2 and a good cycling stability of 92% of the initial specific capacitance after 3000 cycles, which may be considered a prospective material for high-performance electrochemical capacitors.

Highly ordered mesoporous NiCo2O4electrode material exhibited superior electrochemical performances with high specific capacitance and excellent cycling stability.
