| 摘 要： | 利用活性炭模板剂制备了氧化还原催化剂LaMnO3,采用X射线衍射、透射电子显微镜和比表面积分析仪( BET) 等分析手段对催化剂进行了表征,通过循环伏安、线性扫描、蓝电测试等测试方法对LaMnO3电化学性能进行了测试分析。实验结果表明：利用活性炭模板法所制备出的LaMnO3-AC比表面积(20.561 m2/g)远大于共沉淀制备的LaMnO3(8.486 m2/g),并且所制备出的LaMnO3具有良好ORR催化活性。这为相关催化剂材料的设计和研究提供了实验依据和理论基础。

| Abstract: | The REDOX catalyst LaMnO3 was prepared by using activated carbon template agent. The catalyst was characterized by X-ray diffraction, transmission electron microscope and BET, and the electrochemical performance of LaMnO3 was tested by cyclic voltammetry, linear scanning and blue electric test. The experimental results showed that the specific surface area of LAMNO3-AC prepared by activated carbon template method (20.561m2 /g) was much larger than that prepared by coprecipitation (8.486m2 /g), and the prepared LaMnO3 had good ORR catalytic activity. This provides experimental and theoretical basis for the design and research of related catalyst materials. |
