Abstract

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.
