Stepwise synthesis of symmetric and asymmetric Anderson-polyoxometalates for light-driven hydrogen evolution

Abstract

A new strategy to assemble multifunctional Anderson-type polyoxometalate platforms for the light-driven hydrogen-evolution reaction (HER) is presented. The stepwise coordination of precursor metal complexes enables binding of an Ir photosensitizer or a Pt HER catalyst to the bipyridine coordination site. Light-driven HER reactivity for the Pt-equipped species in homogeneous solution is reported together with initial stability analyses.
