摘要
采用水热辅助液相沉积方法,在不同反应温度条件下原位合成TiO2/MXene复合材料。利用X射线衍射技术、扫描电镜以及透射电镜表征所合成样品的物相结构与微观形貌,分析和总结实验工艺条件,并研究复合材料作为电极材料的电化学性能。结果表明,水热温度为130℃时制备得到的TiO2/MXene复合材料,具有最优的循环伏安曲线、恒电流充放电及电化学阻抗谱等电化学性能。
TiO2/MXene composites were synthesized in-situ by hydrothermal-assisted liquid phase deposition at different reaction temperatures.X-ray diffraction,scanning electron microscopy and transmission electron microscopy were used to characterize the phase structure and morphology microstructure of the synthesized samples.The experimental process conditions were analyzed and summarized,and the electrochemical properties of the composites as electrode materials were studied.The results show that TiO2/MXene samples prepared at 130℃had the best electrochemical properties such as cyclic voltammetry curve,galvanostatic charge-discharge and electrochemical impedance spectra.
