Regeneration and Degradation in a Biomimetic Polyoxometalate Water Oxidation Catalyst.

ABSTRACT: Complete understanding of catalytic cycles is required to advance the design of water oxidation catalysts, but it is difficult to attain, due to the complex factors governing their reactivity and stability. In this study, we investigate the regeneration and degradation pathways of the highly active biomimetic water oxidation catalyst [Mn³⁺ ₂Mn⁴⁺ ₂V₄O₁₇(OAc)₃]^3-, thereby completing its catalytic cycle. Beginning with the deactivated species [Mn³⁺ ₄V₄O₁₇(OAc)₂]^4- left over after O₂ evolution, we scrutinize a network of reaction intermediates belonging to two alternative water oxidation cycles. We find that catalyst regeneration t
