Synthesis of Ti(OH)OF ⋅ 0.66 H₂ O in Imidazolium-based Ionic Liquids.

ABSTRACT: The influence of the cation of imidazolium-derived ionic liquids (ILs) on a low-temperature solution-based synthesis of hexagonal tungsten bronze (HTB) type Ti(OH)OF ⋅ 0.66 H₂ O and bronze-type TiO₂ (B) is investigated. The IL (C_x mim BF₄ ) acts as solvent and also as reaction partner with respect to the decomposition of [BF₄ ]^- , releasing F^- . In the present study, the chain length of the alkyl chain side groups attached to the imidazolium ring was varied (C₂ mim BF₄ to C₁₀ mim BF₄ ), and the obtained solids were analyzed by Powder X-Ray diffraction (PXRD) followed by Rietveld refinement. As a main finding these analyses indicate a transformation of Ti(OH)OF ⋅ 0.66 H
