Abstract

Sandwich polyoxometalate [WCo3(H2O)2(CoW9O34)2]12− (Co-WCo3) heterogenized with poly(vinyl butyl imidazolium) cations (PVIM+) acts as a stable electrochemical water oxidation catalyst in 1 M KOH with 0.28 V@10 mA cm−2 overpotential and TOF of 6.16 s−1. Various in situ spectroelectrochemical studies and control experiments provide the details of the catalytic activities and long-term stability of the catalyst.
