Solvent effect to modulate nitrogen dopant in Co-N-C catalysts for oxygen reduction reaction acceleration

Unraveling a volcanic relationship of Co/N/C@PtxCo catalysts toward oxygen electro-reduction

“…Combined with the volcanic relationship in ORR MA, it is concluded that an appropriate Pt content in Co/N/C@Pt x Co catalysts is required to regulate the formation of pyrrolic N and pyridinic N; the pyrrolic and pyridinic N likely play an important role in facilitating the ORR on Co/N/C@Pt x Co catalysts. 51–53…”
