▎ 摘　　要

Very recent progress on the graphene derivatives supported variable nanocatalysts for oxygen reduction reaction (ORR) in fuel cell is reviewed. First, common electrochemical techniques to characterize graphene-based electrocatalysts are mentioned. Second, recent updates on graphene-derived electrocatalysts are introduced. In this part, both electrochemical activity and stability of Pt catalysts can be improved when they are supported by reduced graphene oxide (RGO). Other noble-metal catalysts including Pd, Au, and Ag showing comparable performance have been investigated. The stability of Pd catalyst is enhanced by RGO or few-layered graphene support. Synthetic approaches for Au or Ag catalysts supported on graphene oxide are discussed. In addition, non-noble transition metals in N-4-chelate complexes can reduce oxygen electrochemically. Fe and Co are cheap alternative catalysts for ORR. In most cases, the stability and tolerance issues are overcome well, but their overall performances don't seem to surpass Pt/C catalyst yet.
