ABSTRACT = {An eco-friendly one-pot hydrothermal method was developed to synthesize molybdenum disulfide/graphene oxide (MoS<sub>2</sub>/GO) nanocomposites for high-performance supercapacitor applications. X-ray diffraction (XRD) analysis confirmed the presence of the MoS<sub>2</sub> crystalline phase, with reduced peak intensities upon GO incorporation, indicating suppressed crystallite growth. Scanning electron microscopy (SEM) revealed rod-like MoS<sub>2</sub> structures uniformly distributed across layered GO sheets, and energy-dispersive spectroscopy (EDS) confirmed the presence of Mo, S, C, and O elements. Raman and FTIR analyses verified strong interfacial interactions between MoS<sub>2</sub> and GO. Brunauer–Emmett–Teller (BET) measurements revealed a mesoporous structure with a specific surface area of ~31.7 m<sup>2</sup> g<sup>−1</sup> and a pore size centered at ~4 nm, facilitating efficient ion transport. Electrochemical performance evaluated using cyclic voltammetry (CV) in 2 M KOH electrolyte demonstrated a high specific capacitance of 185 F g<sup>−1</sup> at 5 mV s<sup>−1</sup>. The quasi-rectangular CV curves and symmetric charge–discharge profiles indicate a combined electric double-layer and pseudocapacitive behavior. The MoS<sub>2</sub>/GO composite also exhibited improved charge transfer properties and superior cycling stability over 10,000 cycles compared to pristine MoS<sub>2</sub>. Density functional theory (DFT) calculations revealed that graphene oxide has a higher density of states near the Fermi level than MoS<sub>2</sub>, indicating enhanced quantum capacitance and faster electron-transfer kinetics. The synergistic integration of MoS<sub>2</sub> and GO thus improves conductivity, structural stability, and electrochemical performance. These findings highlight the potential of MoS<sub>2</sub>/GO nanocomposites as efficient electrode materials tailored for high-performance energy storage devices.},
