Abstract:
The development of nonprecious catalyst for oxygen reduction reaction (ORR) is important for the commercialization of the alkaline fuel cells (AFCs). Herein, we prepared a kind of Co‐based nanoparticles (NPs) with a core‐shell (Co@CoO) structure supported on the N‐doped graphene (Co@CoO/NG) as an efficient ORR catalyst via simply pyrolyzing the ZIF‐67 anchored on the synthesized graphene oxide (GO). The catalytic activity for ORR of the obtained Co@CoO/NG is comparable with the state‐of‐art Pt/C catalyst in terms of the onset and half‐wave potential in the alkaline solution. In addition, the Co@CoO/NG exhibited an excellent ORR durability and antimethanol activity compared to the commercial Pt/C. This research would provide a simple strategy to prepare the high‐performance nonprecious metal‐based catalysts for AFCs.
