| Abstract: | This paper discussed the electrochemical behaviours for the passivation ofa copper electrode in NaOH solution. It has been found that the formation ofinsoluble Cu_2O and CuO at electrode surface is the reason for the occurrence ofpassivation. The mechanism for forming Cu_2O at the electrode surface is consideredto be as follows. Cu OH~-[Cu(OH)]ads e~- (1) [Cu(OH)]ads OH~-Cu(OH)_2~- (2) Cu(OH)_2~- CuCu_2O H_2O c~- (3)Reaction(3) is the rate-determining step. |
