Synthesis of nickel molybdate (NiMoO4) by hydrothermal method for supercapacitor application
摘要
Nickel molybdate (NiMoO4) was synthesized via hydrothermal route and employed as an electrode to supercapacitor applications. Synthesized NiMoO₄ powder was thoroughly characterized to investigate its chemical compositional, morphological, structural, and electrochemical studies. X-ray diffraction (XRD) investigation detected the crystalline phase, with a prominent diffraction peak corresponding to the (220) plane of NiMoO₄. Scanning electron microscopy (SEM) revealed the formation of well-defined rod-like structures, which is highly beneficial for electrolyte diffusion and charge storage. The synthesis parameters significantly influenced the material’s morphology, thereby affecting its electrochemical behavior of the electrode material. Electrochemical testing conducted in 1 M KOH electrolyte delivered a specific capacitance upto 368 F/g at 1 A/g current density, it indicates pseudocapacitive nature of NiMoO₄ material. These results focuses the impact of NiMoO₄ as a capable material for high-performance energy storage devices.
