Abstract In this work, the Cu-Sn-Pb bronze samples with similar structure and composition to ancient bronzes were obtained by electroplating method. The samples were aged by artificial corrosion using chemical corrosion solution. And then we compared the corrosion rates of bronze samples before and after artificial corrosion under different atmospheres (N₂, O₂, air). In order to evaluate the influence of five main corrosion pro-ducts (CuCl, Cu₂(OH)₂CO₃, Cu₂(OH)₃Cl, Cu(OH)₂, and CuO) on the corrosion process of bronze artifacts, the electrochemical testing platform was used. Three types of electrode structures, such as the bronze sample electrode, glass carbon electrode and porous electrode, were employed to test the electrocatalytic oxygen reduction activity of the above five corrosion products. The potentiodynamic polarization, electrochemical impedance spectroscopy, polarization and cyclic voltammetry tests were performed. The results revealed that CuCl exhibited the highest catalytic activity for the oxygen reduction reaction among the corrosion products. Based on these findings, we proposed the porous oxygen electrode catalytic model during the corrosion process of bronze artifacts.

Key words： bronze corrosion product oxygen reduction reaction porous oxygen electrode
