An improved catalytic activity has been observed in terms of higher values of onset and half-wave potentials, with larger kinetic currents and low hydrogen peroxide yields. The activity upon comparing with Pt/C with simultaneous experiments shows impressive results. Within the double annealed samples a comparative study has been done on the basis of active sites available for the oxygen reduction reactions. We have revealed the origin of its activity by intensively investigating the composition and the structure of the catalyst and their correlations with the electrochemical performance. ? 2017 Hydrogen Energy Publications LLC |
