Organic-Inorganic Hybrid Co-Containing Polyoxotungstates as Oxygen Evolution Catalyst

Abstract

Herein, the cobalt is incorporated into polyoxotungstates (POWs) to obtain a new organic-inorganic hybrid Co-containing POW with a reliable 1D nanowire structure. The Co-containing POW exhibits superior oxygen evolution reaction (OER) activity in a neutral medium compared with its isomorphic Zn-containing POW, highlighting the critical role of cobalt in enhancing OER performance . This work provides a new insight into the structure-property relationship of metal oxides in electrocatalysis.
