摘要

This study focuses on the hydrothermal synthesis of MnFe2O4 (MFO) with a two-dimensional nanosheet morphology and its integration with MXene to enhance electrochemical performance. Structural characterization through x-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM) confirmed the successful formation of MFO with an average crystallite size of 13.2 nm and nanosheet thickness of ~ 50 nm. MXene exhibited a well-defined layered architecture with an average wall thickness of ~ 92 nm. Its incorporation resulted in strong interfacial interactions with MFO. Electrochemical tests revealed that the specific capacitance increased from 261 F/g for pristine MFO to 673 F/g for the MXene-modified electrode at a current density of 2 mA/cm2. The composite electrode retained 82.5% of its capacitance after 1000 cycles, indicating good cycling stability. These findings underscore the importance of structural optimization and demonstrate that even pristine MFO delivers notable capacitive performance due to its accessible 2D morphology.
