In situ electrochemical quantification of active sites in Fe–N/C non-precious metal catalysts

Fe-N/C catalysts show surprising activity towards oxygen reduction in fuel cells. However, there is significant uncertainty as to the structure of the active site. Here, the authors quantify the number and turnover frequency of the active sites by reversibly blocking those sites with nitrite (NO2¯)....
