文摘

Me–N–C catalysts for ORR synthesized using Me-phthalocyanines (Me = Fe, Co, Cu, Zn). SBA-15 silica used as sacrificial template nano-reactor during pyrolysis. Different metals influence the physical–chemical properties of Me–N–C catalysts. ORR activity in alkaline medium decreases in the order Fe > Co > Cu > Zn ≈ H. Micropores, pyridinic-N and pyrolysis de-H2 temperature linked to the ORR activity.
