Abstract: The depletion of fossil fuels and the growing demand for sustainable energy solutions necessitate advanced materials for energy storage. This study addresses the challenge of improving supercapacitor performance by developing a hybrid composite of Ti 3 C 2 T x MXene and reduced graphene oxide (rGO). The integrating rGO as a conductive bridge impacts the structural stability and electrochemical properties of Ti 3 C 2 T x. Ti 3 C 2 T x MXene was synthesized from Ti 3 AlC 2 MAX phase via selective etching of aluminum, followed by mixing with rGO in ethanol at varying ratios to prepare Ti 3 C 2 T x @rGO composites. The incorporation of rGO minimizes volumetric strain during charge-discharge cycles and enhances conductivity by serving as a nanoscale current collector. Characterization using SEM, TEM, Raman spectroscopy, BET, and XRD confirmed the successful formation of the composite with improved structural integrity. Electrochemical tests, including cyclic voltammetry, galvanostatic charge-discharge, and electrochemical impedance spectroscopy, demonstrated a substantial enhancement in specific capacitance. Notably, the (Ti 3 C 2 T x) 90 (rGO) 10 composition achieved a capacitance of 357 Fg-1 at 1 Ag-1, compared to 220 Fg-1 for pristine Ti 3 C 2 T x. This study highlights the uniqueness of leveraging rGO as a conductive bridge to improve MXene-based supercapacitors, providing a promising pathway for next-generation energy storage solutions with enhanced performance and durability. • High Energy Supercapacitor. • MXene and rGO composites in developing advanced supercapacitors with superior performance. • Conductive Linking Bridge. • Electrochemical properties of Ti 3 C 2 T x @rGO composites.
