Non-precious Fe/N/C catalysts have attracted increased attention due to their activity in oxygen reduction reaction (ORR). To promote the activity of this type of catalysts, we applied the electrochemical treatment of the Fe/N/C sample synthesized by using the known technique. We demonstrated that two-stage anodic-cathodic treatment of the Fe/N/C sample under the certain condition leads to increase the electrocatalytic activity toward the ORR of the starting catalyst. The results may open the opportunities in finding new ways of increasing the activity of Fe/N/C catalysts by using the electrochemical treatment.
