A novel Ta/W mixed-addendum polyoxometalate with photocatalytic properties†
Abstract
An unprecedented polytantalotungstate (POTT), Cs12.5K4.5H[Ta12Si4W37O158]·25H2O (1), based on the {SiW9Ta3O40}7− cluster was hydrothermally synthesized. A photocatalytic study revealed that 1 exhibits significant photocatalytic water splitting activity.
