摘要：燃料电池具有发电效率高、污染噪音小、运行可靠等优势,能够作为新能源汽车的主要动力来源,因此受到各国的广泛关注。氧还原反应(ORR)作为燃料电池中重要的电化学反应,对催化剂有较高的要求,然而目前广泛使用的Pt催化剂存在高成本和低耐久性的问题,限制了新能源汽车的发展。采用非Pt催化剂或低Pt催化剂可以实现在性能不变的前提下降低成本,是推进燃料电池汽车商业化应用的关键。通过金属有机框架材料(MOF)研制的无金属催化剂和过渡金属催化剂可完全替代贵金属Pt催化剂,其中利用ZIF系列制备的MOF基Fe系和Co系催化剂是ORR研究的热点。受非贵金属催化剂的启发,低Pt催化剂通过MOF实现负载或合金化,进一步提升了低Pt催化剂的电化学活性及耐久性。本文就近期基于MOF材料的ORR催化剂研究进展进行综述,介绍了无金属催化剂、过渡金属催化剂和贵金属催化剂的研究现状及面临的挑战,为获得性能优越的ORR催化剂提供了技术支持。
With the advantages of high power generation efficiency,low pollution and noise,and reliable operation,fuel cells have attracted widespread attention from various countries as they can be used as the main power source for new energy vehicles.Oxygen reduction reaction(ORR),as an important electrochemical reaction in fuel cells,has higher requirements on catalysts.However,the high cost and low durability of Pt catalyst used widely restrict the development of new energy vehicles.Non-Pt catalysts or low-Pt catalysts can reduce costs while maintaining the same performance,which is the key to promoting the commercial application of fuel cell vehicles.Metal-free catalysts and transition metal catalysts prepared by metal-organic framework materials(MOF)can completely replace precious metal Pt catalysts.Among them,the Fe-based and Co-based MOF catalysts developed using the ZIF series are the focus of ORR research.In addition,inspired by non-precious metal catalysts,low-Pt catalysts are supported or alloyed through MOF,which further improves low-Pt catalysts electrochemical activity and durability.This paper reviews the recent research progress of ORR catalysts based on MOF materials,introduces the research status and challenges of metal-free catalysts,transition metal catalysts and precious metal catalysts,and provides technical support for obtaining ORR catalysts with superior performance.
