The study titled “Electrochemical and Defect Characterization of APTES-Functionalized Ti3C2Tx MXene for Supercapacitor Devices” prepared by SUNUM researcher Mina Namvari, was published in NANO-MICRO Small by invitation.
This work comprehensively investigates the structural, surface, and electrochemical properties of MAX phase, MXene, and (3-aminopropyl)triethoxysilane-functionalized MXene (APTES-MXene) electrodes. The study developed a high-performance electrode design by APTES functionalization without incorporating conductive polymers, metal oxides, or carbon additions. The findings in the two-electrode system revealed that the APTES-MXene electrode exhibited a specific capacitance of 207.62 F g−1, an energy density of 28.83 Wh kg−1, and a capacity retention of 93.8%. The increase in charge transfer resistance following APTES modification in the EIS data signifies the creation of a more complicated ion transport structure due to the functional surface groups of the material and an extended interlayer distance.
