Microperoxidase-11(MP-11) was adsorbed on active carbon by equilibrium adsorption method. The electrocatalytic behaviors of MP-11/C electrode for the reduction of O₂ and H₂O₂ were studied by cyclic voltammmetry and linear voltammmetry and RDE technique. The results showed that MP-11/C possessed good electrocatalytic activity for the reduction of O₂ and H₂O₂. And the mechanism of oxygen reduction is dependent on pH of the solution. It provides a reliable method for immobilization of enzymes and a promising catalyst for the reduction of O₂ in biofuel cell.
