Self-Assembly and Visible-Light Photocatalytic Properties of W/Nb Mixed-Addendum Polyoxometalate and Transition-Metal Cations.

Making light work: Three novel W/Nb mixed‐addendum polyoxometalates, which all contain the {SiNb3W9O40} cluster, have been synthesized by conventional aqueous methods. Visible‐light photocatalytic H2 evolution activity (see figure) was observed for two of the compounds, with H2PtCl6 as a cocatalyst and triethylamine as a sacrificial electron donor.
