摘要

本研究采用水热法合成了Ti3C2Tx/MoS2 （MXMS）纳米复合材料，并对其作为超级电容器电极材料的电化学性能进行了评价。该策略为提高电容性能和增加表面积提供了一条有前途的途径，从而提高了用于储能应用的电极材料的效率。在Ti3C2TX MXene薄片中掺入MoS2有效地抑制了层堆积，并促进了电荷转移动力学的改善。因此，在1 M H2SO4电解质中，Ti3C2Tx/MoS2纳米复合材料在1 a /g电流密度下可提供595 F/g的高比电容。此外，该复合材料在5a /g充放电循环2000次后仍保持82%的初始电容，表现出优异的电化学稳定性。此外，利用x射线衍射（XRD）、场发射扫描电镜（FESEM）、布鲁诺尔-埃米特-泰勒（BET）和x射线光电子能谱（XPS）对合成材料的结晶度、形貌、表面积和成分分析进行了研究。

Enhanced supercapacitor performance of Ti3C2Tx/MoS2 heterostructure

In this study, hybrid nanocomposite of Ti₃C₂T_x/MoS₂ (MXMS) was synthesized via hydrothermal method and evaluated for its enhanced electrochemical performance as a supercapacitor electrode material. This strategy offers a promising pathway to enhance capacitive performance and increase surface area, thereby improving the efficiency of electrode materials for energy storage applications. The incorporation of MoS₂ into Ti₃C₂T_X MXene sheets effectively inhibits layer restacking and facilitates improved charge transfer kinetics. Consequently, Ti₃C₂T_x/MoS₂ nanocomposite delivers a high specific capacitance of 595 F/g at a current density of 1 A/g in 1 M H₂SO₄ electrolyte. Furthermore, the composite retains 82 % of its initial capacitance after 2000 charging-discharging cycles at 5 A/g, demonstrating excellent electrochemical stability. Additionally, X-ray diffractogram (XRD), Field Emission Scanning Electron Microscopy (FESEM), Brunauer-Emmett-Teller (BET) and X-ray Photoelectron Spectroscopy (XPS) were utilized to investigate crystallinity, morphology, surface area, and composition analysis of as-synthesized materials.
