摘要

This study presents a novel nanocomposite (rGO/MoS₂@CZS) consisting of CoZnS (CZS) and MoS2 integrated into a reduced graphene oxide (rGO) matrix. The morphology, structure, surface area, and optical properties of the synthesized materials were analyzed using SEM, XRD, BET, and UV–vis spectra. The electrochemical performance of the (rGO/MoS₂@CZS) hybrid electrode was evaluated using a standardized three-electrode setup. The hybrid electrode demonstrates remarkable electrochemical performance, exhibiting a high specific capacity (Qs) of 1237 C/g at 1.5 A/g and outstanding cycling stability with 92.9% retention after 12,000 cycles. The fabricated asymmetric device (rGO/MoS₂@CZS//AC) attains a high energy density of 71.73 Wh/kg and a power density of 960 W/kg. In addition, the MoS2/CZS@rGO composite displays excellent photocatalytic activity under light conditions. These results highlight the synergistic benefits of MoS2, CoZnS, and rGO integration, making rGO/MoS₂@CZS a promising candidate for multifunctional energy storage devices.
