Controlled synthesis of Co3O4@NiMoO4 core–shell nanorod arrays for efficient water splitting

Abstract

Exploitation of environmentally friendly electrocatalysts for a robust oxygen evolution reaction (OER) in an alkaline medium is very satisfactory. Here, a very low cell voltage of 1.65 V is acquired when Co₃O₄@NiMoO₄/NF is firstly used as a bifunctional water splitting catalyst with 10 mA cm⁻² in 1.0 M KOH.
