Potentiodynamic examination of surface processes and kinetics for the Ag2O/AgO/OH− system

摘要: Abstract A detailed examination of the Ag 2 O/AgO/OH − system with linear potentiodynamic and trapezoidal control electrode potential shows a non-stoichiometry for AgO formation approximately 1 in 6 silver atoms Ag(III) state. An autocatalytic reaction accounts from O at constant potential, provided that is initiated by electrochemical production number sites. Reduction first-order specific rate k = 3·2 ± 0·9 × 10 −3 s −1 , transfer coefficient α 0·55. The reduction mechanism 3+ + 2e → agreement results obtained using steady state conditions.
