中文摘要：

应用电化学方法将钴（Ⅱ）卟啉氧化成钴（Ⅲ）卟啉以增强它与4-巯基毗啶（MP）自组装膜的轴向配位作用，从而快速制备了有序钴卟啉自组装修饰电极CoTMPP／MP／Au（E）．电化学石英晶体微天平（EQCM）测试证实电化学氧化对钴卟啉膜生长过程的增强作用．Raman光谱及修饰电极电催化还原氧研究显示，该修饰电极与经过长时间浸渍法得到的CoTMPP／MP／Au（Ⅰ）修饰电极具有完全相似的有序结构和性质．与直接将钴卟啉吸附在电极表面的CoTMPP／Au修饰电极相比，以巯基吡啶为桥键得到的钴卟啉修饰电极具有更好的电催化活性和稳定性。

英文摘要：

According to the different coordination ability between Cobalt （Ⅱ） porphyrin and Cobalt （ Ⅲ ） porphyrin, an electrochemical modulated self-assembling process was developed to prepare the CoTMPP/MP/Au （E） modified electrode. The O2 reduction catalytic activity and the Raman spectrum of the CoTMPP/MP/Au （E） modified electrode were found to be similar to those of the CoTMPP/MP/Au（Ⅰ） modified electrode obtained by the immersion method, which was suggested that both modified electrodes have the similar well oriented structure and electrochemical behavior. Compared with CoTMPP/Au modified electrode, the modified electrodes with mercaptopyridine ligand were showed better electrocatalytic activity and stability.
