Developing inexpensive catalysts with plentiful active sites and high surface area to accelerate the oxygen reduction reaction (ORR) is of great significance for metal-air batteries. Nevertheless, it is still a challenge to balance the content of active sites and the high surface area of catalysts, especially in a versatile and economical way. Herein, a single-atom Fe catalyst was prepared by pyrolyzing biomass aerogels that anchor iron ions through coordination reactions. With the synergistic effect of a large surface area and a high Fe content, the optimized catalyst FeNC-900-8 shows excellent ORR activity and stability. The Zn-air battery with catalyst FeNC-900-8 as the cathode delivers a high peak power density and discharge voltage. This work offers a facile strategy to develop single-atom catalysts with a high surface area and a moderate metal content for high-performance ORRs. (C) 2021 Elsevier Ltd. All rights reserved.
