文摘
- •
Synergy of methanol and oxygen-containing groups in Fe-based catalysts is discovered.
- •
The synergy can be practically controlled by the content of oxygen-containing groups.
- •
The synergy enhances the current density of oxygen reduction reaction by 21.6%.
- •
Fe-based catalysts show a synergy-induced current density 16.8% higher than Pt/C.
- •
The synergy works in assembled anion-exchange membrane fuel cell systems.
