Abstract

A COOH-terminated nitrogen-doped carbon aerogel exhibited 100% selectivity to two-electron oxygen reduction, exceeding reported carbonaceous and noble metal catalysts. The optimal electrode with the synergistic effect of C–N/C–COOH resulted in a minimum ηO₂/H₂O₂ and gave an evolution rate of 60 mg L⁻¹ g⁻¹ h⁻¹ for H₂O₂ with satisfactory mechanical and electrochemical stability for practical applications.
