Ligand-Mediated Proton-Coupled Electron Injection into Reactive Cores of Soluble Macroanion-Like Complexes of Titanium Dioxide.

ABSTRACT: Although widely utilized as reactive components of devices and functional materials, the harnessing of metal-oxide nanocrystals (NCs) as ligand-tunable reaction centers of soluble catalysts remains an ongoing challenge. We now report that readily modifiable, oxidatively inert polyoxometalate (POM) ligands amplify and rationally control rates of photocatalytic H₂ evolution by anatase-TiO₂ NCs. This was achieved using a series of four POM-derived oxo-donor ligands, [(Xⁿ⁺W₁₁O₃₉)Ti^IV-O^-]^(10-n)-, Xⁿ⁺ = Al³⁺, Si⁴⁺, P⁵⁺, and [(P₂W₁₇O₆₁)Ti^IV-O^-]^8- (written here as oxo-anion donors) coordinated via bridg
