摘要

In this study, we have synthesized a MoS2–Gd2O3 nanostructure via a two-step hydrothermal method to develop a high-performance electrode material for supercapacitor (SC) applications. The synthesized MoS2–Gd2O3 nanostructure was examined using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), field-emission scanning electron microscopy (FESEM), and X-ray photoelectron spectroscopy (XPS) to identify its crystalline structure, functional groups, morphology, and elemental/chemical state composition, respectively. Incorporating Gd2O3 provides a conductive route for ion passage and offers structural support throughout charge and discharge cycles. The synergistic interplay between the excellent conductivity of MoS2 and the redox-active properties of Gd2O3 presents an excellent opportunity for significantly enhancing the charge-storage capacity of MoS2–Gd2O3 nanostructure. This synergistic effect further contributes to improved overall performance in energy storage applications. The MoS2–Gd2O3 nanostructure displays a specific capacitance of 180 F/g at 1 A/g and retained 80% after 1000 cycles, indicating good stability. This work highlights the potential of the MoS2–Gd2O3 nanostructure as a potential electrode material for SC applications.
