摘要

The oxygen reduction reaction (ORR) is a crucial process in fuel cell systems, and techniques that will enable high-efficiency ORR are challenging and elusive. Here, we report N-doped carbon materials prepared by the medium temperature molten salt method that not only exhibit remarkable ORR performance with a high onset potential, half-wave potential and small Tafel slope comparable to those of state-of-the-art Pt/C catalysts, but also possess long-term stability. This work represents a solid step toward high-efficiency oxygen reduction.
