摘要

Two novel 3D extended polyoxotantalates/niobates solid complexes: [Na₆(H₂O)₁₃)][Li(H₂O)(H₃O)][(Ta₆O₁₉)] (1) and [Na₆(H₂O)₁₃][Li(H₂O)₂][H(Nb₆O₁₉)] (2) have been assembled successfully based on double alkali metal ions (Li⁺ and Na⁺) and Lindqvist clusters ([Ta₆O₁₉]^8-/[Nb₆O₁₉]^8-) under aqueous solution. Both compounds have been characterized by IR, TG analysis and single-crystal X-ray diffraction. It is worth noting that Li and Na ions, different kinds of alkali ions, are first observed coexisting in two resultant solid crystal structures of polyoxotantalates/niobates. Further photocatalytic investigations show that methylene blue (MB) dye solution can be degraded by UV irradiation effectively in the presence of [Nb₆O₁₉]^8-/[Ta₆O₁₉]^8-. The experiments indicate that the degradation efficiency depends on pH value, irradiation time, initial MB concentration and different types of POM anions etc.
