A core-shell structured CoMoO₄•nH₂O@Co_1-xFe_xOOH nanocatalyst for electrochemical evolution of oxygen.

ABSTRACT: Nickel-iron oxyhydroxide (Ni_1-xFe_xOOH) is well recognized as the best-performing oxygen evolution reaction (OER) catalyst in alkaline electrolytes, however its analogue cobalt-iron oxyhydroxide (Co_1-xFe_xOOH) is surprisingly less explored despite their structural similarity. Inspired by our recent study on high-performance HER catalyst using the nanostructured CoMoO₄•nH₂O precursor, herein, we report a facile synthesis of Co_1-xFe_xOOH catalyst derived from the same precursor and its excellent electrocatalytic properties towards the OER in alkaline electrolytes. A core-shell structured nanocatalyst consisting of disordered Co_1-xFe_xOOH layer over the surface of crystalline CoMoO_4<
