Nanocrystalline TiO2 with pure rutile and pure anatase phases was prepared at moderate reaction temperatures by hydrolysis of TiCl4 in different air- and water-stable ionic liquids with the same anion ([Py1,4]Tf2N, [EMIM]Tf2N, and [P14,6,6,6]Tf2N), in isopropanol and in cosolvent of ionic liquid/isopropanol under different reaction conditions. The type of cation in the ionic liquid influences the morphology of the rutile phase: cone-like morphology was obtained in the case of [Py1,4]+ and [P14,6,6,6]+ ions and wormhole-like in the case of [EMIM]+. In the case of anatase, no significant effect was found. The influence of various reaction conditions like acidity of solution, solvent type, precursor type, and precursor concentration on the phase formation and morphology of titania were investigated.

Three kinds of functionalized imidazolium ionic liquid, 1-chloride (2-hydroxyethyl) -3-methyl imidazole ionic liquid [HeMIM]Cl, 1-bromide ethylamine-3-methyl imidazolium ionic liquid [AeMIM]Br and chlorinated 1-carboxyethyl-3-methyl imidazolium ionic liquid [CeMIM]Cl, were synthesized firstly. Subsequently, three kinds of supported silicon imidazolium ionic liquids were prepared from above ionic liquids with tetraethoxysilane by sol-gel method. The Chemical structure and crystal structure of the supported on silica based ionic liquids were analyzed by FTIR and XRD.
