Abstract

Abstract : Sandwich polyoxometalate [WCo3 (H2 O)2 (CoW9 O34 )2 ] 12− (Co-WCo3 ) heterogenized with a poly(vinyl butyl imidazolium) cation (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 . Abstract : Sandwich polyoxometalate [WCo3 (H2 O)2 (CoW9 O34 )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.
