Assembling of polyoxometalates with chalcogenides metals nanohybrid as competent electrocatalyst for high performance supercapacitors

The low electrochemical efficiency and low cycle resilience of materials for electrodes limit the use of energy-storing devices like batteries in addition to super-capacitors. The Preparation of nanocomposite materials to increase specific surface area furthermore conductive properties has become essential to achieving noticeably soaring performance and stability that is vital criteria designed for evaluating the material of electrodes in favor of supercapacitor applications. The current effort synthesizes a Cu₃Mo₂O₉/WS₂ nanohybrid using a straightforward and affordable coprecipitation method. Through the use of X-ray powder-diffraction techniques (XRD), Fourier transform infrared spectroscopy (FT-IR), and scanning of electron microscopy (SEM), the geometry, chemical composition, energy state like oxidation and morphological concepts of synthesized materials Cu₃Mo₂O₉, WS₂ and Cu₃Mo₂O₉/WS₂ nanohybrid were examined. All manufactured materials' elemental composition was verified using x-ray spectroscopy with energy dispersive technology (EDX). The morphology within the nanohybrid is enhanced by the addition of WS₂ nanoflowers to Cu₃Mo₂O₉ nanosheets. The nanohybrid (Cu₃Mo₂O₉/WS₂) demonstrated exceptional stability (1000 cycles), specific capacitance (1380 F g⁻¹), as well as specific energy (47.26 Wh Kg⁻¹) over a current density about 2.5 A g⁻¹, as determined by a triple electrode galvanostatic charged discharge (GCD) system, thanks to its enhanced morphology. Furthermore, the Cu₃Mo₂O₉/WS₂ nanohybrid's exceptional electrochemical properties have exciting technological potential for the future.
