Improving platinum group metal–free oxygen reduction ...

2021-2-1  There is a great focus in the platinum group metal–free (PGM-free) electrocatalyst community on what sites are responsible for activity in high-temperature treated, heterogeneous M–N–C (M = Mn, Fe, Co) systems [1, 2, 3, 4].These materials are capable of catalyzing the oxygen reduction reaction (ORR) that takes place at proton exchange fuel cell cathodes.
