论文简介如下：
The innovative design of highly active and noble-metal-free electrocatalysts for oxygen reduction reaction (ORR) is urgently required for the widespread application of Zinc-air batteries (ZABs). In this work, a porous composite is developed by integrating N and S co-doped carbon aerogels with Co9S8 nanoparticles as ideal ORR electrocatalysts (denoted as Co9S8@NSC). It is revealed that the unique porous carbon aerogels with a high specific surface area provide abundant catalytic sites and efficient channels for the reactants and electrolytes while maintaining the uniform distribution of nanoparticles over a long period of operation. Meanwhile, the cooperation of ORR-active Co9S8 nanoparticles and N and S co-doped carbon aerogels has an important significance for ORR performance improvement. Based on the above advantages, Co9S8@NSC demonstrates a competitive ORR activity with high half-wave potential (E1/2, 0.85 V), fast electron transfer kinetics (Tafel slop, 53.3 mV dec-1), and prominent long-term stability. When used as an air cathode catalyst in primary Zn-air batteries, the Co9S8@NSC electrode displays a power density of 150.9 mW cm-2 and a specific capacity of 735 mAh gzn-1.
