Synthesis and characterization of hybrid materials based on 1-butyl-3-methylimidazolium tetrafluoroborate ionic liquid and Dawson-type tungstophosphate K-7[H4PW18O62] . 18H(2)O and K-6[P2W18O62] . 13H(2)O KU Leuven
In this study, we synthesized hybrid materials using well-Dawson polyoxometalates (POMs), K-7[H4PW18O62] center dot 18H(2)O or K-6[P2W18O62] center dot 13H(2)O and a room temperature ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4]). K, W, P and CHN elemental analysis showed that one mole of [H4PW18O62](7-) reacts with 6 moles of BMIM+ and one mole of [P2W18O62](6-) reacts with 4 moles of BMIM+ to form, respectively, ...
