摘要:

 采用共沉淀法和高温煅烧制备了AlMn复合氧化物、FeMn复合氧化物、ZnMn复合氧化物和BiSn复合氧化物,采用X射线衍射仪和扫描电子显微镜对产物的物相结构、形貌等进行了表征;并将4种复合氧化物作为铝–空气电池空气电极催化剂进行了恒流放电、循环伏安、交流阻抗、阴极极化测试。结果表明:所制备的4种复合氧化物形貌皆不同。除AlMn复合氧化物外,其他3种复合氧化物都具有较好的催化性能。FeMn复合氧化物组成的电极活性最差。用ZnMn复合氧化物制备的电池在20 mA/cm2的电流密度下电压平台高达1.46 V,在100 mA/cm2电流密度下还能保持0.72 V,相比其他3种复合氧化物其性能最佳。
