High Active Hollow Nitrogen‐Doped Carbon Microspheres for Oxygen Reduction in Alkaline Media

Abstract

Abstract Dopamine, a sustainable and cheap raw material, was selected as the carbon and nitrogen sources to synthesize hollow nitrogen‐doped carbon microspheres (HNCMS). The obtained HNCMS were used as a non‐noble‐metal electrocatalyst for oxygen reduction in alkaline solution and show high electrocatalytic activity, excellent long‐term stability, and tolerance to crossover effect of methanol.
