N, S Codoped Iron-carbon-based Electrocatalyst for Oxygen Reduction Reaction via Salt Recrystallization Strategy
We prepared a kind of iron-carbon-based non-precious catalyst doped with N and S simultaneously (Fe/N/S/C) by using a salt recrystallization method. The electrochemical test results demonstrated that the Fe/N/S/C catalyst obtained by the salt recrystallization method showed a much better catalytic activity for ORR than that without using the salt recrystallization under the acidic condition. The Fe/N/S/C catalyst also exhibits an excellent ORR stability and anti-methanol activity.
