Efficient water oxidation with electromodified Langmuir-Blodgett films of procatalytic [Co(III)(N2O3)] metallosurfactants on electrodes.
Electromodified Langmuir-Blodgett films of a phenolate-rich [Co(III)(L(N2O3))H2O] metallosurfactant support water oxidation at an overpotential of 0.5 V. Gradual enhancement of catalytic activity is observed between 1 and 9 deposited layers. Upon application of a potential bias the molecular species rearranges into a catalytic layer that yields estimated turnover numbers of 54 000 ± 1500 h(-1).
