摘要
由于高效,低温操作以及零污染排放等特性,质子交换膜燃料电池被认为是有前景的电动车替代电源。最近,丰田公司在美国正式推出了燃料电池汽车(Mirai)。然而,当前电极催化剂高昂的价格以及不稳定性仍然阻碍着燃料电池汽车的进一步市场推广。怎样发展低价,高效的燃料电池催化剂?当前主要的解决方案有三:(1)发展新型的铂基纳米结构;(2)发展更加稳定的载体材料;(3)发展非铂基的,非贵金属甚至非金属的催化剂。在这个报告中,将介绍我们在非金属的氧气还原反应催化剂的研究进展。内容涉及从掺氮碳纳米管到掺氮石墨烯,以及共掺杂石墨烯的制备,表征及性能研究;着重介绍怎样进一步设计杂原子掺杂石墨烯材料以提高催化剂的活性;最后也提出一些在该类催化剂研究中常常被忽视的问题,供大家参考。
Polymer electrolyte membrane fuel cells are considered promising alternative power sources for transportation due to their high efficiency,low temperature operation,and zero emissions.Recently,Toyota put their commercial fuel cell car(Mirai) into North American markets.However,currently the high cost and insufficient durability still hinder the further commercialization of fuel cells.How to develop the low-cost and high efficient electrocatalysts for fuel cells? The main solutions include:(1) developing the novel Pt-based nanostructures;(2) developing more stable supports;(3) developing non-Pt,non-noble metal,even metal-free electrocatalysts.In this presentation,we will introduce the research progress of metal-free electrocatalysts for oxygen reduction reaction(ORR) in our group,which covers the synthesis,characterization and electrochemical performance of nitrogen doped carbon nanotubes,graphene,and co-doped graphene.The emphasis is placed on the discussion on how to design doped graphene materials for further improving their ORR performances.At the last,we also give some prospects for development opportunities of this kind of materials.
