Abstract:The exploration of noble metal free bifunctional oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) electrocatalysts is very important for Zn-air batteries (ZABs). Spinel ferrites are famous bifunctional ORR/OER electrocatalysts. Herein, to further improve their ORR and OER activities, we anchor CoFe2O4 on N-doped carbon nanofibers (NCNF) derived from polypyrrole (PPy) and obtain CoFe2O4 loaded NCNF (CoFe2O4@NCNF). In its structure, CoFe2O4 particles with small size distribute evenly on NCNF. … Show more
