英文摘要	We report an insitu electrochemical scanning tunneling microscopy (ECSTM) investigation of the 5,10,15,20-tetraphenyl-21H,23H-porphine cobalt(II) (CoTPP)-catalyzed oxygen reduction reaction (ORR). A highly ordered CoTPP adlayer is revealed on the Au(111) electrode. High-contrast adsorbed species are monitored in CoTPP adlayer in electrolyte containing oxygen, and are attributed to the formation of CoTPP-O-2 complexes. Insitu STM results reveal the sharp contrast changes upon switching the substrate potential to trigger the ORR. The results benefit the understanding of the catalytic role of metal porphyrins (MPs) in the ORR, which is important for the design of MP-based catalysts.
