Engineering heme-copper and multi-copper oxidases for efficient oxygen reduction catalysis
Fuel cell draws increasing attention because of its high theoretical efficiency (over 90%). However, the actual efficiency is limited by the large overpotential (500-600 mV) of the oxygen reduction reaction (ORR), which demands a potent ORR catalyst to decrease the overpotential. Towards this goal, …
