| Abstract: | We have synthesized Ti3C2TX MXene, a two-dimensional material for energy storage applications. The Ti3C2TX MXene was synthesized from Ti3AlC2 using a mixture of hydrochloric acid and lithium fluoride in contrast to the conventional highly toxic hydrofluoric acid-based method. Further, the etching conditions, such as temperature and reaction time, were optimized to obtain well-defined exfoliated MXene sheets. The results revealed that a temperature of 60 °C and an etching duration of 45 h yielded successful exfoliation and the formation of Ti3C2TX MXene with a hexagonal structure and an average grain size of 27 nm. Fourier-transform infrared and UV–Vis spectroscopy confirmed the presence of -O, -OH, and -F functional groups, and a direct bandgap of 2.01 eV was determined for MXene sheets. Electrochemical analyses demonstrated a high specific capacitance of 600 F/g at a 20-mV/s scan rate and a specific capacitance of 315 F/g at a current density of 0.5 A/g, along with an energy density and power density of 28 Wh/kg and 160 W/kg, respectively. These findings underscore the potential of Ti3C2TX MXene as a high-performance material for energy storage applications, while highlighting the advantages of a safer and ecofriendly process.
