In the present study, Cu3(MoO4)2(OH)2 electrode materials were prepared by CTAB assisted hydrothermal method. Thermal, crystalline and bonding properties of freshly prepared samples were confirmed by thermo gravimetric analysis (TGA), x‐ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR) and Raman analyses. The surface morphological features of Cu3(MoO4)2(OH)2 electrode materials were observed via Scanning electron microscopy (SEM) analysis. The concentration of cetyl trimethyl ammonium bromide (CTAB) template has much influenced in nanomaterial formation and the high concentration (3 mM) of CTAB provides nanorod structures. The electrochemical analysis of Cu3(MoO4)2(OH)2 electrodes were demonstrated via cyclic voltammetry (CV), chronopotentiometry (CP) and cyclic stability analyses. The electrochemical investigations of Cu3(MoO4)2(OH)2 electrode provide remarkable specific capacitance of 532 F g−1 at a scan rate of 5 mV s−1 and good cyclic stability of 98 % retention even after 5000 cycles at a scan rate of 20 mV s−1 with good rate capability. These outcomes prompted to assign a probable application for the synthesized Cu3( MoO4)2(OH)2 to utilize as a capable electrode material for supercapacitor applications.

高性能超级电容器电极用Cu3(MoO4)2(OH)2纳米棒的简便合成与表征

在本研究中,通过CTAB辅助水热法制备了Cu 3(MoO 42(OH)2电极材料。通过热重量分析(TGA),X射线衍射分析(XRD),傅立叶变换红外光谱(FTIR)和拉曼分析确定了新制备样品的热,晶体和键合特性。Cu 3(MoO 42(OH)2的表面形态特征通过扫描电子显微镜(SEM)分析观察电极材料。十六烷基三甲基溴化铵(CTAB)模板的浓度对纳米材料的形成有很大影响,高浓度(3 mM)的CTAB提供了纳米棒结构。通过循环伏安法(CV),计时电位法(CP)和循环稳定性分析证明了Cu 3(MoO 42(OH)2电极的电化学分析。Cu 3(MoO 42(OH)2电极的电化学研究以5 mV s -1的扫描速率提供了532 F g -1的明显比电容。甚至在20 mV s -1的扫描速率下经过5000次循环后仍具有98%保留率的良好循环稳定性,具有良好的速率能力。这些结果促使人们为合成的Cu 3(MoO 42(OH)2指定了可能的应用,以用作超级电容器应用的有能力电极材料。
