摘要
燃料电池作为新一代清洁高效能源转换系统受到了极大的关注,但燃料电池阴极氧气还原动力(ORR)学十分缓慢,目前所用的铂基催化剂成本昂贵,稳定性差,限制了燃料电池未来的发展。杂原子掺杂的碳材料已被证明是可替代铂基催化剂的廉价材料,文章通过电纺聚丙烯腈和三聚硫氰酸合成了氮硫共掺杂的碳纳米纤维(N,S-CNF),该材料在碱性条件下表现出良好的ORR电催化活性和稳定性以及优于Pt/C的耐甲醇性。
Fuel cells have received great attention as a new generation of clean and eff icient energy conversion systems,but the oxygen reduction reaction(ORR)of fuel cell cathode is very slow.The platinum-based catalysts currently used are expensive and have poor stability,which limits the future of fuel cells.Heteroatom-doped carbon materials have been proven to be cheap materials that can replace platinum-based catalysts.In this paper,we synthesized nitrogen and sulfur co-doped carbon nanof ibers(N,S-CNF)by electrospinning polyacrylonitrile and thiocyanuric acid.Under alkaline conditions,the material showed good ORR electrocatalytic activity and stability,and superior to Pt/C in methanol resistance.
