摘要：

Oxygen reduction was studied on AISI 304 stainless steel in 0.5 M NaCl solution at pH values ranging from 4 to 10. A rotating disc electrode was employed. It was found that oxygen reduction is under mixed activation-diffusion control. The reaction order with respect to oxygen was found to be one. The values of the Tafel slope depend on the potential scan direction and pH of the solution, and range from - 115 to - 180 mV dec-1. The apparent number of electrons exchanged was calculated to be four, indicating the absence of H2O2 formation.
