In this study, we report on the enhancement of the electrochemical properties of MXene by intercalating C60 nanoparticles between its layers. The aim was to increase the interlayer spacing of MXene, which has a direct effect on capacitance by allowing the electrolyte flow in the electrode. To achieve this, various concentrations of TiSiC (known as MXene) and C60 nanocomposites were prepared through a hydrothermal process under optimal conditions. The resulting composites were characterized by using X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, Raman spectroscopy, and cyclic voltammetry. Electrodes were fabricated using different concentrations of MXene and C60 nanocomposites, and current-voltage (-) measurements were performed at various scan rates to analyze the capacitance of pseudo supercapacitors. The results showed the highest capacitance of 348 F g for the nanocomposite with a composition of 90% MXene and 10% C60. We introduce MXene-C60 composites as promising electrode materials for supercapacitors and highlight their unique properties. Our work provides a new approach to designing high-performance electrode materials for supercapacitors, which can have significant implications for the development of efficient energy storage systems.
在本研究中，我们报告了通过在MXene层间嵌入C60纳米颗粒来增强其电化学性能。目的是增加MXene的层间距，这通过允许电解质在电极中流动而对电容产生直接影响。为实现这一目标，在最佳条件下通过水热法制备了不同浓度的TiSiC（即MXene）和C60纳米复合材料。使用X射线衍射、扫描电子显微镜、能量色散光谱、拉曼光谱和循环伏安法对所得复合材料进行了表征。使用不同浓度的MXene和C60纳米复合材料制备电极，并在不同扫描速率下进行电流-电压（-）测量，以分析赝超级电容器的电容。结果表明，组成为90%MXene和10%C60的纳米复合材料具有最高电容，为348 F g。我们将MXene-C60复合材料作为超级电容器有前景的电极材料进行介绍，并突出其独特性能。我们的工作为设计用于超级电容器的高性能电极材料提供了一种新方法，这可能对高效储能系统的发展产生重大影响。
