Abstract

Layered LiCo0.8 Fe0.2 O2 demonstrates dramatically enhanced oxygen evolution reaction (OER) activity and durability in an alkaline solution over LiCoO2 and other reported state-of-the-art catalysts, including benchmark IrO2 . This superior performance is attributed to Fe-doping-induced synergistic effects.

Keywords: electrocatalysis; electrocatalysts; lithium cobalt oxides; oxygen evolution reactions; synergistic effects.
