Based on the data available from electrochemical evaluations, the density of current (as an important factor for evaluating the efficiency of the catalyst in energy production), the number of electrons exchanged and the selectivity of the catalyst are excellent due to the regular structure of the composite. The number of electrons exchanged for the oxygen reduction reaction in alkaline medium was estimated to be about 1.98 - 2.01 in the high and low excess potentials; nearly fixed number of exchanged electrons(about ±1 percent of error) indicates excellent selectivity of catalyst for dual-electron path of Oxygen reduction reaction and the lack of hydrogen peroxide re-entry, produced in oxidation-reduction reactions, and its limited amphoteric behavior.
