摘要
本研究探索了通过水热工艺合成棒状锰铜钴(MCC)复合材料,从而产生视觉上吸引人的形态。通过各种技术对合成的MCC纳米复合材料进行表征。分析证实了过渡金属氧化物在金属复合材料中以所需的氧化态存在。对棒状MCC复合材料的电化学性能进行了评价。结果显示了令人印象深刻的伪电容特性,在5 mv−1下具有670.31 Fg−1的高比电容和出色的循环稳定性,即使在5000次循环后仍保持91% %的电容。进一步的计算表明,MCC复合材料具有显著的面比电容(231.38 mFcm - 2)、能量密度(0.0157 mWh cm - 2)和功率密度(0.1487 mW cm - 2)。这些发现证明了形态良好的MCC复合材料作为电化学超级电容器储能电极材料的潜力。
Investigating the enhanced nanostructures of MnO2/CuO/Co3O4 for their potential use as electrodes in supercapacitor application
This study explores the synthesis of rod-like manganese-copper-cobalt (MCC) composites through a hydrothermal process, resulting in visually appealing morphologies. The synthesized MCC nanocomposites characterization through various techniques. The analysis confirmed the incorporation of transition-metal oxides in metallic composites in the desired oxidation states. The electrochemical performance of the rod-like MCC composites was evaluated. The results revealed impressive pseudocapacitance characteristics, with a high specific capacitance of 670.31 Fg−1 at 5 mVs−1 and excellent cycling stability, retaining 91 % capacitance even after 5000 cycles. Further calculations demonstrated notable areal-specific capacitance (231.38 mFcm−2), energy density (0.0157 mWh cm−2), and power density (0.1487 mW cm−2) for the MCC composites. These findings demonstrate the potential of well-morphologically established MCC composites as capable electrode materials for energy storage in electrochemical supercapacitors.
