Electrochemical performance and optimization of α-NiMoO4 by different facile synthetic approach for supercapacitor application

Spherical copper molybdate (Cu3Mo2O9 ) nanoparticles (NPs) have been prepared via the microwave combustion technique. The structural, morphological and elemental characterizations have been investigated by PXRD, SEM and EDS studies. It was found that the as-prepared sample possesses nanoplate morphology and particles size was found to be around 18 nm. The as-prepared sample was inspected in the disintegration of Methylene Blue (MB) dye envisioned using UV-Visible spectroscopy. It was found that the prepared nanocatalyst could serve as an active photocatalyst for MB under direct sun light.

Energy perception and Energy consumption are major consideration in daytoday life in every place in world. Electrochemical energy storage devices are best remedies to fullfil the energy consumption and also serve as a alternate energy source of renewable energy devices. Here, Ni3V2O8 is developed by hydrothermal process. The crystalline phase, sixe and structural properties are identified using X- ray Diffraction techniques. The functional group and molecular bond formations are analysed using Fourier transform Infrared spectroscopy. The prepared Ni3V2O8 nanoparticles are most applied for electrode of supercapacitor applications.

“…This preparation strategy is exceptional as it has numerous favourable circumstances like upgraded response energy, specific materials coupling, quick volumetric warming, high response rate, expanded item yield, most virtue item, and so forth than traditional strategies. Moreover, this technique can suppress the by-products during preparation [2], [4], [5], [14] Bi 2 MoO 6 nanoplates has been prepared by a simple microwave combustion method as depicted earlier [2], [4], [5]. Bi(NO 3 ) 3 .5H 2 O, Na 2 MoO 4 .2H 2 O and CO(NH 2 ) 2 (1:1:4 molar ratio) were each dissolved together in 50 mL of DD water under magnetically stirred in ambient condition.…”

Orthorhombic structured bismuth molybdate (Bi2MoO6) is obtained by one pot microwave combustion method. The characteristic performance of Bi2MoO6 nanocatalyst are described by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) furnished with Energy - dispersive X-ray spectroscopy (EDS) and Fourier change infrared (FT-IR) spectroscopy. The average crystallite size for Bi2MoO6 estimated from XRD is about 28.9 nm. The surface morphology from SEM pictures displays nanoplates. The FTIR is utilized to recognize the structural coordination and the presence of functional group. The electrochemical studies are taken to readily comprehend the electrochemical performance of the modified active electrode with notable specific capacitance value are found 234.9 Fg-1 at 5 mVs-1 and cyclic retention is stable up to 900 cycles (98.7 %). The as-synthesized dynamic material acts as a novel electrode material for supercapacitor.
