摘 要: 高效的双功能催化剂能够大幅提高金属空气电池的动力学过程。使用共沉淀法成功制备CuCo2O4尖晶石氧化物,并通过扫描电子显微镜(scanning electron microscope,SEM)观测发现其具有板栗壳状结构,这种结构能增加其表面电化学活性位点,使其在旋转环盘电极(rotating-ring-disk electrode,RRDE)测试中表现出优秀的氧化还原反应(oxygen reduction reaction,ORR)和氧气析出反应(oxygen evolution reaction,OER)催化性能。
关 键 词: 二次能源;能源储存和转化;双功能催化剂;尖晶石;锂空气电池

Abstract: Efficient bifunctional catalyst can sharply improve the dynamic process of metal-air battery. Herein, spinel oxide CuCo2O4 has been synthesized by coprecipitation method. The chestnut shell structure of the sample is observed by scanning electron microscope (SEM), of which the structure can increase surface electrochemical active sites. The rotating-ring-disk electrode (RRDE) results show that the as-prepared CuCo2O4 exhibits excellent oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) catalytic activities.
Key words: secondary energy; energy storage and conversion;bifunctional catalysts; spinel; Li-air battery
