摘要："The low specific surface area and insufficient exposure of active sites are usually the key reasons for the poor oxygen reduction reaction of catalysts. Here, we update a new method, using NaCl as a template, egg white as a carbon source and nitrogen source, adding FeCl3 as an iron source, and adopting a two-step pyrolysis method to synthesize a sponge-like porous Fe-N-C catalyst. This kind of three-dimensional sponge-like catalyst exhibits more defective structures, so it shows an excellent electrochemical performance with a half-wave potential of 0.73 V and onset potential of 0.88 V. Additionally, the catalyst has amazing stability, which proves that it is a promising candidate for green energy devices. Our research provides an innovative method to synthesize high-performance Fe-N-C catalysts using low-cost common biomaterials."
