- Description
- This work explores the rational design and synthesis of a high-performance ternary nanocomposite rGO/CeO2/PPy, by incorporating cerium oxide and polypyrrole into the rGO matrix, through a hybrid approach of combining hydrothermal synthesis with in situ oxidative polymerization. Comprehensive structural characterization of the rGO/CeO2/PPy composite confirms the successful integration of components, revealing a hierarchically porous architecture that optimizes both charge transport and ion diffusion kinetics. The ternary composite exhibits exceptional interfacial interactions, including ?-? conjugation between rGO and PPy, coupled with electrostatic stabilization from CeO2, resulting in enhanced mechanical integrity and improved electrolyte accessibility. Electrochemical characterization reveals remarkable performance metrics, with a specific capacitance of 874 F g?1 and outstanding cyclic durability of 94% capacity retention after 5000 charge-discharge cycles at 1 A g?1. The configured rGO/CeO2/PPy//AC system exhibits exceptional energy storage performance, yielding an energy density of 39.6 Wh kg?1 while sustaining a power density of 2859 W kg?1. These outstanding characteristics underscore the material's suitability as a cutting-edge electrode for sophisticated energy storage systems, showcasing the benefits of strategic component integration in hybrid nanocomposite design. 2025 The Royal Society of Chemistry.
