摘要：

The oxygen electroreduction on electrodes with adsorbed peroxidase (POD) or a POD-Nafion composite is studied. In the conditions of direct bioelectrocatalysis, the process occurs on both POD and POD in the composite. The higher the electrode coverage by POD, the higher the measured current. The composite electrodes have a higher activity and stability. A mechanism of the cathodic reduction of oxygen by immobilized POD is discussed.
