摘　　要：以五水硝酸铜,对苯二甲酸,2-氨基嘧啶,科琴黑为原材料,通过水热法及惰性气氛下煅烧过程得到产物CuMOF-x(x=1,2,3)。重点研究了单配体对苯二甲酸、2-氨基嘧啶、二元混合配体对产物的氧还原催化性能的影响。利用电化学工作站,采用线性扫描伏安法对其氧还原催化性能进行测试,并采用Koutecky-Levich方程对其氧还原电子转移数进行计算。研究结果表明,含氮单配体2-氨基嘧啶对产物氧还原催化性能的影响要优于羧酸单配体对苯二甲酸配体,而两者的二元混合配体效果最佳;所制得的3种催化剂CuMOF-x(x=1,2,3)催化氧气还原均以4e^-途径进行。CuMOF-x(x=1,2,3) was obtained by hydrothermal method and calcination under inert atmosphere with cupric nitrate pentahydrate,terephthalic acid,2-aminopyrimine and ketjenblack 600 as raw materials.The effects of terephthalic acid,2-aminopyrimidine and binary hybrid ligand on the catalytic properties of the products were deeply studied.The catalytic performance of oxygen reduction (ORR)as-prepared catalysts was measured by linear scanning voltammetry using electrochemical workstation,and the electron transfer numbers of oxygen reductions were calculated by Koutecky-Levich equation.The result showed that 2-aminopyrimidine nitrogen-containing ligand had better effect than that of terephthalic acid ligand on the catalytic performance for ORR,and the binary mixed ligand of the two had the best effect.The as prepared three catalysts CuMOF-x(x=1,2,3) all catalyzed oxygen reduction reaction through a 4e^-pathway.
