文摘
- •
A novel sulfur-nitrogen doped ordered mesoporous carbon (SN-OMC) was prepared.
- •
S and N content in SN-OMC can be tuned by simply adjusting the precursors feeding content.
- •
S1N5 -OMC exhibits similar 4e−-ORR activity and better CH3OH tolerance and stability as to Pt/C.
- •
The synergistic effect between S and N is beneficial for improving ORR activity.
