Novel MoSe3 nanomaterial was effectively synthesized by the Solvothermal method. The prepared nanomaterials were examined by X-ray Diffraction, UV-Visible Spectroscopy, Fourier Transform Infrared Spectroscopy, Field Emission Scanning Electron Microscopy, Energy-Dispersive X-ray Spectroscopy, and X-ray Photoelectron Spectroscopy analysis. The crystallite size and the optical band gap energy of MoSe3 nanomaterial were determined to be 32 nm and 1.57 eV, respectively. The functional groups and elemental metal presence were identified by FTIR analysis. The rod-like structured morphology and flake-like layers were observed in FESEM analysis. The XPS study identified the oxidation states of Molybdenum as +6 and Selenium as −2, which confirmed the phase as MoSe3. The electrochemical performance of the MoSe3 electrode coated in nickel foam and aluminium foil was analysed by EIS, GCD, and CV studies, and the capacity retention of 105% after 1500 cycles for the MoSe3 nickel foam electrode was observed. It confirmed its ideal capacitive behaviour for supercapacitor applications. The MoSe3 electrode prepared on Nickel foam exhibits superior electrochemical performance compared to Aluminium foil, with higher specific capacitance (776 F/g) and lower resistance (11.18 Ω), indicating better suitability for supercapacitor applications.
