- Description
- This study presents the first investigation into the effect of reduced graphene oxide (rGO) on the electrochemical properties of rGO-MoO? nanocomposites, synthesized via the hydrothermal method. The nanocomposites were prepared with varying rGO concentrations, and their structural, morphological, elemental, electrical, optical, and surface characteristics were analyzed. Structural analysis confirmed the presence of an orthorhombic MoO? phase, while the morphological analysis revealed MoO? nanobars anchored onto rGO nanosheets. The electrochemical performance of the nanocomposites was evaluated using a three-electrode configuration. The electrode demonstrating superior performance was selected to fabricate a prototype symmetric device. This device exhibited a specific capacitance of 369 F g?1 at a current density of 1 A g?1 and an energy density of 51 W h kg?1. Moreover, the device demonstrated a stability of 91% over 1000 cycles with a coulombic efficiency of 104%. 2025 Hydrogen Energy Publications LLC
