摘　　要：采用中性或准中性溶液为电解质的锌-空气电池具有提高阳极锌稳定性并避免电解质溶液碳酸盐化的优点。开发新型非贵金属催化剂,使之在中性溶液中能有效催化氧还原反应(ORR),这将具有重要意义。通过总结近几年铁/钴/镍掺杂的碳氮复合物的制备、ORR活性测试以及应用于中性锌-空气电池的性能研究方面的主要工作成果,发现采用简单的热解法得到的具有管状结构的非贵金属掺杂的碳氮复合物可以成为中性锌-空气电池优异的阴极催化剂。The Zn-air batteries using the neutral or quasi-neutral solution as the electrolyte has the advantages of improving the stability of the anode zinc and avoiding carbonation of the electrolyte solution.It is significant to develop novel non-precious catalysts with efficient electroactivity for oxygen reduction reaction(ORR)in neutral solution.The progress of the preparation of Fe/Co/Ni doped C-N composites,their ORR electroactivity tests and application for neutral Zn-air battery was summarized.The non-precious metals doped C-N composites obtained by simple pyrolysis present typical hollow tubular structure and are the excellent cathodic catalysts of neutral Zn-air battery.
