摘要:
采用溶胶-凝胶法制备网状多孔CoO催化剂,并采用X线衍射仪(XRD)、场发射扫描电子显微镜(FESEM)、透射电子显微镜(TEM)、比表面积分析(BET)和电化学测试等手段对样品进行了表征。结果表明:CoO催化剂对氧的氧化-还原反应具有良好的双向催化效果,降低了电化学极化,展现出平坦的充放电平台(3.6 V),提高锂氧气电池的比容量至7 450 mA·h/g,并且改善了循环稳定性。
Abstract:
Network porous cobalt oxide catalyst was synthesized via a sol-gel method.The porous CoO catalyst was characterized by X-ray diffraction(XRD),field emission scanning electron microscopy(FESEM),transmission electron microscopy(TEM),BET and electrochemical measurements.The electrochemical performance was exhibited by the Li-O2 cells with porous CoO catalyst.The awful electrochemical polarization was alleviated and a flat discharge/charge plateau was showed by CoO based Li-O2 cells.The specific capacity of Li-O2 cells was raised to 7 450 mA·h/g and the cycle performance was also improved by the porous CoO catalyst.
