title = "Oxygen electro-reduction on C22 and C276 nickel metal alloy",
abstract = "The C22 and C276 alloy metal surfaces were characterized for electrochemical activity in alkaline aqueous media in the presence and absence of oxygen (O2) and at 30° C The metal was studied by electrochemical impedance spectroscopy (EIS), voltammetry with a still electrode and a specialized rotating ring-disk electrode (RRDE) technique, the cyclic potential ring measurement (CPRM) method (1). The CPRM method gave the steady state O2 reduction kinetics. An initial study of O2 reduction on gold yielded virtually identical results to the work of Vilambi and Taylor who first described the CPRM method. The application of the CPRM method to the study of O2 reduction on C22 and C276 showed strong evidence for a predominantly series 2 step, 2 electron O2 reduction pathway, where kinetic rate constants k2 (evaluated at - 0.7V versus the saturated calomel electrode) and k3 (evaluated at - 1.2V) were estimated at 30°C to be 0.001 cm/s and 0.193 cm/s respectively for C22 and 0.013 cm/s and 0.232 cm/s respectively for C276. copyright The Electrochemical Society.",
