摘　　要：(C70 ) 2 对叔丁基杯 [8]芳烃化学修饰电极在V(乙腈 )∶V(水 ) =2∶3混合溶剂中 ,发生两步还原 /再氧化反应 ,分别对应于两电子和四电子转移 .用扫描电子显微镜和光电子能谱对修饰电极进行了表征 .循环伏安实验表明 ,(C70 ) 2 对叔丁基杯 [8]芳烃的两步还原过程均对卤代酸的还原具有电催化作用 .The (C 70) 2-p-tert-butylcalixarene chemically modified electrode had two couples of redox reactions in mixed solvents of MeCN and water (2∶3, volume fraction), corresponded to two- and four-electron transfer, respectively.The modified electrode was characterized by the scanning electron microscope and X-ray photoelectron spectroscopy. Both the reduction steps of (C 70) 2-p-tert-butylcalixarene exhibited catalytic activity towards the reduction of halogenated acid.
