Abstract

In this paper, the two-dimensional multilayered Ti₃C₂T_x-MXene was obtained by hydrofluoric acid etching method on the bulk phase material MAX(Ti₃AlC₂) substrate. The two-dimensional multilayered Ti₃C₂T_x-MXene/PPy-NW composite electrode materials were successfully prepared by combining the one-dimensional polypyrrole nanowires (PPy-NW) with two-dimensional multilayered Ti₃C₂T_x-MXene. The morphologies and compositions of the synthetic materials were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). Electrochemical tests showed that Ti₃C₂T_x-MXene/PPy-NW composite electrode material could reach 374 F·g^-1 at a scanning rate of 10 mV·s^-1, which is higher than pure PPy-NW (304 F·g^-1). When the scanning rate increased to 200 mV·s^-1, it could still retain 72.4 % of the original specific capacitance value, showing good multiplying performance. Finally, the Ti₃C₂T_x-MXene /PPy-NW composite electrode material still retained good cycling stability even at high current density of 5 A·g^-1 (91.6% capacitance retention after 2000 cycles). In summary, the composite of two-dimensional multilayered Ti₃C₂T_x-MXene and one-dimensional PPy-NW effectively improved the capacitance performance of electrode materials, and had great application prospect in electrochemical energy storage.
