Immobilization of a [Co^IIICo^II(H₂O)W₁₁O₃₉]^7- Polyoxoanion for the Photocatalytic Oxygen Evolution Reaction.

ABSTRACT: The ongoing transition to renewable energy sources and the implementation of artificial photosynthetic setups call for an efficient and stable water oxidation catalyst (WOC). Here, we heterogenize a molecular all-inorganic [Co^IIICo^II(H₂O)W₁₁O₃₉]^7- ({Co^IIICo^IIW₁₁}) Keggin-type polyoxometalate (POM) onto a model TiO₂ surface, employing a 3-aminopropyltriethoxysilane (APTES) linker to form a novel heterogeneous photosystem for light-driven water oxidation. The {Co^IIICo^IIW₁₁}-APTES-TiO₂ hybrid is characterized using a set of spectroscopic and microscopic techniques to reveal the POM integrity and dispersion to elucidate the POM/APTES and APTE
