Abstract

Graphene–Gd₂O₃ nanocomposites were synthesized by incorporating varying concentrations of reduced graphene oxide (rGO) into Gd₂O₃ using a straightforward room-temperature solution method. The composites were analyzed using various distinct characterization techniques, including X-ray diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). Electrochemical measurements, particularly cyclic voltammetry (CV), demonstrated that the incorporation of graphene significantly enhanced the electrochemical performance of the composites, with Gd₂O₃G5 exhibiting a high specific capacitance of 26.4 Fg⁻¹ at a scan rate of 10 mV/s. The photocatalytic activity of the composites was evaluated by the degradation of methylene-blue (MB) dye under UV light, showing improved photocatalytic performance with higher graphene content. These results suggest that graphene–Gd₂O₃ nanocomposites hold significant potential for applications in energy storage systems and environmental remediation technologies. The findings underscore the importance of interface engineering in enhancing the electrochemical properties of graphene-based metal oxide nanocomposites. The graphene–Gd₂O₃ system presented in this study shows considerable promise as an efficient electrode material for next-generation supercapacitors and other advanced energy storage devices. Controlled synthesis strategies were employed to optimize particle size, dispersion, and interfacial interactions between graphene sheets and Gd₂O₃ nanoparticles, leading to improved charge transfer kinetics and ion diffusion pathways.

Keywords: Cyclic voltammetry, electrochemical properties, energy storage, environmental remediation, Gd₂O₃, graphene, methylene-blue degradation, nanocomposites, photocatalysis
