A Comprehensive Study on the Dye Adsorption Behavior of Polyoxometalate-Complex Nano-Hybrids Containing Classic β-Octamolybdate and Biimidazole Units.

ABSTRACT: Six new hybrids based on β-[Mo₈O₂₆]^4- polyoxometalates, [Ni(H₂biim)₃]₂[β-Mo₈O₂₆]•8DMF(1); (DMA)₂[M(H₂biim)₂(H₂O)₂][β-Mo₈O₂₆]•4DMF (M = Ni (2), Co (3)), DMA = dimethyl-ammonium, H₂biim=2,2'-biimidazole); [M(H₂biim)(DMF)₃]₂[β-Mo₈O₂₆]•2DMF (M = Zn (4), Cu (5)); [(DMA)₂[Cu(DMF)₄][β-Mo₈O₂₆]•2DMF]_n (6), have been successfully synthesized and characterized. Compounds 2⁻5 show favorable capacity to adsorb methylene blue (MB) at room temperature, and they can selectively capture MB molecules from binary-mixture solutions of MB/MO (MO = Methyl Orange), or MB/RhB (RhB = Rhodamine B). Compound 3 can uptake up to 521.7 mg g^-1 MB cationic dyes rapidly, which per
