摘　　要：合成了4,4′,4″,4″′—四硝基酞菁合钴(Ⅱ),并进行了表征,用不可逆吸附法制备了该化合物为修饰物的化学修饰电极,以光电子能谱法进行了表面表征。并研究了分子氧在该化学修饰电极上的电化学行为,发现该化学修饰电极对氧的还原有明显的电催化作用。Cobalt 4 ,4' ,4',4''' - tetranitro phthalocyanine (CoTNPc)was synthesized and characterized. Its chemically modified electrode was prepared and characterized. The electrochemical behaviors of the CoTNPc CME were studied. The electrocatalytical reduction of dioxygen was investigated. We proposed that Co(II)/Co(l)redox sites at the CoTNPc CME transported electrons from the glass carbon electode to the absorbed dioxygen molecules to electrocatalytically reduced dioxygen.
