Evidence for the stabilization of FeN4 sites by Pt particles during acidic oxygen reduction

Evidence for the stabilization of FeN4 sites by Pt particles during acidic oxygen reduction

Abstract While Fe–N–C materials have shown promising initial oxygen reduction reaction (ORR) activity, they lack durability in acidic medium. Key degradation mechanisms include FeN4 site demetallation and deactivation by reactive oxygen species. Here we show for mainstream Fe–N–Cs that adding 1 wt.%...
