EQCM and RDE/RRDE study of soluble iron phthalocyanine bifunctional catalyst for the lithium-oxygen battery
Soluble iron phtalocyanine (FePc) has been studied as a bifunctional catalyst for the oxygen reduction reaction (ORR) and oxygen evolution (OER) in lithium air cathodes by means of electrogravimetry with shear wave dissipation, cyclic voltammetry (CV) and rotating ring disk electrode (RRDE). The oxy...
