Hydrothermal Method–Derived MnMoO 4 Crystals: Effect of Cationic Surfactant on Microstructures and Electrochemical Properties

The development of energy devices is becoming necessary to deal with the power crisis. Binary transition manganese molybdate (MnMoO 4 ) is considered to be a well‐known material for storage applications. Electrochemical performance of anode electrode materials was tested with respect to the effect of cationic surfactant cetyltrimethylammonium bromide (C 19 H 12 BrN). The fundamental characterization studies such as X‐ray diffraction, photoluminescence, Raman, and Fourier transform infrared confirmed the presence of MnMoO 4 . The scanning electron microscopic (SEM) images revealed well‐grained micro/nanostructures. The electrochemical behavior was determined by cyclic voltammetry (CV), galvanostatic charge‐discharge (GCD), and electrochemical impedance spectroscopy studies. In this study, 0.2 M CTAB/MnMoO 4 showed high 447.61 F/g specific capacitance from the CV analysis. The GCD studies showed that after 3000 cycles, the cycling stability was retained with 79.60% of capacitive retention.
