Abstract
- Heteroatom doped porous carbons have been regarded as one of most promising candidates for Pt-free oxygen reduction reaction (ORR) catalysts. The proper heteroatom bonding configuration and synergistic effect of multiple atom co-doping are very important for improving their catalytic activity. In this work, a series of N, S co-doped porous carbons (NSCs) with excellent ORR performance were prepared by rationally using a dual-ligand metal organic framework as a carbon precursor. The interconnected porous structure, high surface area, N, S co-doping and high graphitization-N dopant, significantly contribute to the enhanced catalytic performance of ORR. The electrocatalyst studies indicated that the obtained materials have comparable ORR activity to that of the commercial Pt/C in both alkaline and acidic media, and superior long-term durability than that of Pt/C. This work can provide some guidance for synthesizing other multiple atom co-doping carbons for energy storage and conversion applications through target oriented synthesis of metal organic frameworks with different ligands.
