Abstract
of the Cu-Fe-CN-3 catalyst exhibited a slight negative shift by 5 mV, which was better than the activity loss of the Pt/C catalyst (12 mV). At the same current density, the average discharge platform of Al-air batteries with the Cu-Fe-CN-3 catalyst was better than that of the commercial Pt/C catalyst. Therefore, the prepared Cu-Fe-CN-3 electrocatalyst exhibits great potential as an efficient ORR catalyst in fuel cells.
