Abstract

This study presents the synthesis of TiO-graphene nanocomposites with varying mass ratios of graphene (2.5, 5, 10, 20 wt. %) using a facile and cost-effective hydrothermal approach. By integrating TiO nanoparticles with graphene, a nanomaterial characterized by a two-dimensional structure, unique electrical conductivity and high specific surface area, the resulting hybrid material shows promise for application in supercapacitors. The nanocomposite specimens were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, Raman microscopy, field-emission scanning electron microscopy (FESEM), and transmission electron microscopy (TEM). Additionally, supercapacitive properties were investigated using a three-electrode setup by cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance spectroscopy (EIS) tests. Notably, the TiO-20 wt. % rGO nanocomposite exhibited the highest specific capacitance of 624 F/g at 2 A/g, showcasing superior electrochemical performance. This specimen indicated a high rate capability and cyclic stability (93 % retention after 2000 cycles). Its remarkable energy density and power density of this sample designate it as a strong contender for practical supercapacitor applications.

摘要

本研究采用简便且经济高效的水热法合成了具有不同石墨烯质量比（2.5%、5%、10%、20%重量比）的TiO-石墨烯纳米复合材料。通过将TiO纳米颗粒与石墨烯相结合，得到了一种具有二维结构、独特导电性和高比表面积的纳米材料，所得的杂化材料在超级电容器应用方面显示出潜力。通过X射线衍射（XRD）、傅里叶变换红外（FTIR）光谱、拉曼显微镜、场发射扫描电子显微镜（FESEM）和透射电子显微镜（TEM）对纳米复合样品进行了表征。此外，使用三电极装置通过循环伏安法（CV）、恒电流充放电（GCD）和电化学阻抗谱（EIS）测试研究了超级电容性能。值得注意的是，TiO-20%重量比的还原氧化石墨烯（rGO）纳米复合材料在2A/g电流密度下表现出最高比电容624F/g，展示了优异的电化学性能。该样品显示出高倍率性能和循环稳定性（2000次循环后保持率为93%）。其显著的能量密度和功率密度表明它是实际超级电容器应用的有力竞争者。
