Laboratory evaluation demonstrates enhanced catalytic activity in iron-nitrogen-carbon systems, suggesting viable non-platinum options for fuel cells.
Replacement of expensive and rare platinum with metal-nitrogen-carbon catalysts for oxygen reduction reactions in proton exchange membrane fuel cells is hindered by their inferior activity. Herein, we report a highly active iron-nitrogen-carbon catalyst by optimizing the carbon structure and coordination environments of Fe-N
