Nitrogen-Rich Mesoporous Carbon Nanospheres with Atomic Fe-N4 Sites for Efficient Oxygen Reduction

Key Points

• The aim is to develop non-precious metal electrocatalysts that improve the oxygen reduction reaction efficiency and stability.
• Synthesis of nitrogen-rich mesoporous carbon nanospheres with atomic Fe-N4 sites.
• Electrochemical tests to evaluate the performance of the synthesized materials in the oxygen reduction reaction.
• The newly synthesized electrocatalysts show improved activity and stability for the oxygen reduction reaction.
• The performance metrics indicate a strong potential for use in zinc-air batteries.
