摘要

Developing noble metal-free catalysts with low cost,high performance and stability for oxygen reduction reaction (ORR) in fuel cells is of great interest to promote sustainable energy devices.In this review,we summarized noble metal-free catalysts for ORR,including non-noble metal-based and heteroatom-doped carbon nanomaterials.Mesoporous structure,homogeneous distribution of nanocrystals and synergistic effect of carbon base and nanocrystals/doped heteroatoms have great effect on the ORR property.The noble metal-free nanomaterials showed comparable catalytic property,better stability and methanol tolerance than commercial platinum (Pt)-based catalysts,showing great potential as substitutes for noble metal-based catalysts.In addition,the challenges and chances of developing noble metal-free ORR catalysts are also discussed.
