摘要：

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.
