Spinel ZnCo2O4/N-doped carbon nanotube composite: A high active oxygen reduction reaction electrocatalyst

In this communication, we report on the solvothermal preparation of spinel ZnCo 2 O 4 /N-doped carbon nanotube (ZnCo 2 O 4 /NCNT) composite. As a novel oxygen reduction reaction (ORR) electrocatalyst , the ZnCo 2 O 4 /NCNT composite shows high activity via a four-electron pathway in alkaline solution. Such catalyst also exhibits superior methanol tolerance ability and durability over commercial Pt/C catalyst.
