Synthesis and characterization of synergetic Pd/MoO3–rGO hybrid material as efficient electrode for supercapacitor application
In this work, study synthesized Pd–rGO and Pd/MoO3–rGO nanocomposites via a one-pot hydrothermal method, serving as efficient electrodes for supercapacitor applications. Various analytical techniques, including XRD, XPS, HRTEM, BET, and Raman spectroscopy, were employed to characterize the structural, morphological, and physiochemical properties to assess the electrochemical supercapacitor performance of nanocomposite materials. The analyses confirmed that the charge transfer mechanism between the MoO3-NR with Pd-rGO in Pd/MoO3–rGO samples has significantly improved the electrochemical performance of Pd/MoO3–rGO by 2.7 times compared to Pd-rGO sample (105.00 F/g at 0.5 A/g). Remarkably, the Pd/MoO3–rGO hybrid material exhibited excellent electrochemical activity, boosting a specific capacitance of 291.50 F/g at a current density of 0.5 A/g, accompanied by energy density and power density values of 18.06 Wh/kg and 250.00 W/kg, respectively. Furthermore, it demonstrated noteworthy stability over prolonged usage, retaining 88.46 % of its capacity after 1000 cycles at a constant current density of 1.0 A/g. These findings underscore the promising potential of the Pd/MoO3–rGO nanocomposite as a highly effective electrode material for supercapacitors.
