Özet

This study reports the fabrication of reduced graphene oxide modified Ti3CNTx MXene (Ti3CNTx /rGO) for enhanced supercapacitor performance. The synthesized materials and composites were characterized using XRD, FTIR, SEM/EDS, and XPS spectroscopy. The Ti3CNTx/rGO composite exhibit superior electrochemical performance, achieving a maximum specific capacitance (613 F g−1) at a current density of 1 A g−1. The composite also retains 94.62 % of the capacitance with 92.07 % coulombic efficiency after 5500 cycles in a long-term stability test. Further, it was also confirmed through kinetic analysis that the charge-storage was mainly governed by the diffusion process. This excellent charge storage capacity and long-term stability make the fabricated material a promising candidate for applications in supercapacitors.
