目前,燃料电池中普遍使用的是贵金属铂基催化剂,但其价格昂贵,资源日渐匮乏,严重阻碍了燃料电池的商业化应用,所以寻找低成本、高催化活性和高稳定性的非贵金属催化剂一直是人们关注的研究热点之一。本文阐述了燃料电池非贵金属催化剂在金属氧化物、金属络合物、非金属掺杂的碳基催化剂等三个方面的研究进展,并对其未来的发展趋势提出展望。
At present, precious metal platinum-based catalysts are commonly used in fuel cells. However, their expensiveness and lack of resources severely hampered the commercial application of fuel cells. Therefore, the search for non-noble metal catalysts of low cost, high catalytic activity and high stability has been It is one of the research hot spots that people pay attention to. This article describes the research progress of non-noble metal catalysts for fuel cells in three aspects: metal oxides, metal complexes, and non-metal doped carbon-based catalysts. The future development of fuel cell catalysts is also discussed.
