用阴极还原二价锰和二价钴的方法在碳纤维上共沉积了Mn(OH)2和Co(OH)2前驱物,通过干燥和热处理过程制备了钴掺杂的氧化锰(CMO)。用扫描电子显微镜(SEM)、 X射线衍射(XRD)、 X光电子能谱(XPS)对CMO电极的形貌、结构和元素状态进行表征,用电化学工作站研究了电极材料的电化学性能。结果显示,由于钴原子进入氧化锰晶胞中,增加氧化锰的面间距,改善了氧化锰的电化学性能。%The Mn(OH)2 and Co(OH)2 precursors were co -deposited on the carbon fiber by cathodic reduction from bivalent manganese and cobalt , then Co doped manganese oxide ( CMO) electrodes were prepared by dry and heat treatment.Scan electron microscopy (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) were used to characterize the morphology , structure and elemental state of manganese oxide electrodes . And electrochemical properties were investigated utilizing electrochemical workstation .The results showed that doping cobalt atoms in the unit cell structure of manganese oxide resulted in the increase of interplanar spacing , which enhanced the electrochemical performance of manganese oxides .
