It remains a great challenge to replace platinum‐based catalysts with earth‐abundant materials to accelerate the sluggish oxygen reduction reaction (ORR) at the cathode, which is crucial for the future commercialization of fuel cells. Owing to the high catalytic activity, long‐term durability and low cost, transition metal‐nitrogen‐carbon (M−N/C, M=Fe, Co, Ni, Mn, etc) materials have been widely recognized as the most promising non‐precious metal catalysts (NPMCs) for ORR. In this review, the recent understanding of the ORR catalytic mechanism and the intrinsic nature of active sites is briefly introduced. Then, two crucial factors involved with careful selection of suitable M−N/C precursors and preferable control over the geometric structures of the catalysts are presented. Finally, we provide the insights into the remaining debates and challenges to illuminate the further development of ORR catalysts.

用于氧还原反应的过渡金属-氮-碳催化剂的最新进展

用富地球的材料代替铂基催化剂仍然是一个巨大的挑战，以加速阴极处缓慢的氧还原反应（ORR），这对于燃料电池的未来商业化至关重要。由于高催化活性，长期耐用性和低成本，过渡金属-氮-碳（M-N / C，M = Fe，Co，Ni，Mn等）材料已被广泛认为是最有前途的非金属材料。用于ORR的贵金属催化剂（NPMC）。在这篇综述中，简要介绍了对ORR催化机理和活性位点固有性质的最新了解。然后，提出了两个关键因素，这些因素涉及仔细选择合适的M / N / C前体以及对催化剂几何结构的优选控制。最后，
