Interface self-assembly preparation of multi-element doped carbon nanobowls with high electrocatalysis activity for oxygen reduction reaction.

摘要: Abstract Developing an efficient, stable and low cost oxygen reduction reaction electrocatalyst is desirable for fuel cells metal-air batteries. Here, we have successfully prepared multi-element doped carbon nanobowls by simply mixing the porous sulfur graphitic nitride quantum dots in FeCl3 solution subsequent high temperature treatment processes. Compared with commercial Pt/C electrocatalyst, display a comparable half-wave potential of 0.82 V, much larger limiting diffusion current density (0.4–0.8 V), better methanol-tolerance higher long-term stability alkaline media. The robust three-dimensional structure multiple active centers derived from Fe, N, S O co-doping are responsible excellent performance. This work suggests that such can be promising alternative Pt-based catalysts cells.
