摘　　要：寻求清洁、无污染的新能源是全球可持续发展迫切需要解决的重大课题。直接甲醇燃料电池(direct methanol fuel cells)因其操作温度低、能量效率高、污染排放少及燃料便于运输等优点,受到了人们的普遍关注。其中电极催化剂材料是决定直接甲醇燃料电池性能、寿命和成本的关键因素之一。近年来,纳米碳材料和掺杂技术的兴起有力推动了直接甲醇燃料电池的发展。综述了氮掺杂纳米碳材料在直接甲醇燃料电池电极催化剂方面最新的研究进展,主要对氮掺杂纳米碳材料的制备方法、微结构调控和对甲醇氧化及氧还原反应的促进机理作了详细的评述,并展望了氮掺杂纳米碳材料作为直接甲醇燃料电池电极催化剂的发展趋势。Over past decades,direct methanol fuel cells have attracted considerable attention because they can operate at ambient temperatures and offer ultra-high energy density and fast oxidation kinetics inherent in liquid fuels.One of the key factors in achieving high-energy densities in DMFCs is to design and construct suitable electrocatalysts.Recently,the development of the nanoscale carbon materials and the doping technology gives a significant pathway for the commercial application of DMFCs.In this paper,recent research progresses in nitrogen-doped carbon materials for electrocatalysts of DMFCs have been summarized,mainly focusing on the method,the composition and the microstructure.Especially the facilitated mechanisms have also been discussed.The directions in this field were finally suggested for future research.
