The role of Cu-ion doping in α-MnO₂ electrocatalysts for the oxygen reduction reaction in alkaline electrolyte was investigated. Copper doped α-MnO₂ nanowires (Cu-α-MnO₂) were prepared with varying amounts of Cu²⁺ using a solvothermal method. The electrocatalytic dataindicates that Cu-α-MnO₂ nanowires have higher terminal current densities, enhanced kinetic rate constants, and improved charge transfer resistances that trend with Cu-content, exceeding values attained by α-MnO₂ alone. The observed improvement in catalytic behavior correlates with an increase in Mn³⁺ content for the Cu-α-MnO₂ nanowires. The Mn³⁺/Mn⁴⁺ couple is themediator for the rate-limiting redox driven O₂^-/OH^- exchange. It is proposed that O₂ adsorbs viaan axial site (the e_g orbital on the Mn³⁺ d⁴ ion) at the surface, or at edge defects, of the nanowireand that the increase in covalent nature of the nanowire with Cu-ion doping leads to stabilization of O₂ adsorbates and faster rates of reduction. This work is applicable to other manganese oxide electrocatalysts and shows for the first time there is a correlation for manganese oxides between electrocatalytic activity for the ORR in alkaline electrolyte and an increase in Mn³⁺ character of the oxide.
