Abstract:
In this work, unique structures of mulberry‐like Fe/N/S‐doped nanoporous carbon materials (NCMs) are synthesized via a simple self‐assembly assisted process. The Fe 2+ ‐mediated polymerization of dopamine (DA) and further interaction with triblock copolymer F127 micelles induce the formation of mulberry‐like Fe/PDA/F127 structures. After carbonization, the Fe/N/S‐doped NCMs are obtained with a highly porous structure and large Brunauer‐Emmett‐Teller (BET) surface area of 913.2 m 2 g −1 . Moreover, DA and iron salt introduce active sites, such as Sp 2 C, graphitic N, pyridinic N, Fe−N x , C−S−C, etc. Benefiting from these unique structural features and chemical compositions, the optimized Fe/N/S‐doped NCMs exhibit enhanced electrocatalytic activity and excellent durability for oxygen reduction reaction (ORR) compared with commercial Pt/C catalyst. These studies provide not only a new synthesis method for heteroatom‐doped NCMs, but also a platform for various applications.
