Abstract

Two nanoscale polytantalotungstates (POTTs), Cs₅K₄{Cr₃[Ta₃P₂W₁₅O₆₂]₂(H₂O)₁₂}·15H₂O (1) and Cs_8.5K₈Na₂H_5.5{Cr₄[Ta₃P₂W₁₅O₆₂]₄(H₂O)₁₂}·53H₂O (2), based on unprecedented {Cr₃Ta₆} and {Cr₄Ta₁₂} clusters, respectively, were hydrothermally synthesized. A photocatalytic study revealed that 1 and 2 exhibit significant photocatalytic water splitting activities.
