Description
Summary:•Synthesis of MnMoO4·0.9H2O by simple chemical precipitation scheme.•Comparison of the performance of room-temperature synthesized MnMoO4·0.9H2O and hydrothermally synthesized MnMoO4.•215 F/g at 1 mA/cm2 could be achieve by the MnMoO4·0.9H2O electrode.•MnMoO4·0.9H2O is a promising electrode material for supercapacitor application. A facile room-temperature synthesis method was employed to prepare MnMoO4·0.9H2O nanorods. Electrochemical characterization showed that the sample offered a high specific capacitance of 215 F/g at a current density of 1 mA/cm2 and a low ionic resistance of 0.65 Ω. This performance was higher when compared with hydrothermally synthesized MnMoO4 which had been thermally treated at 300 °C. This makes our room temperature synthesized electrode material an attractive low cost choice for supercapacitor application.
