Facile Sol-Gel Synthesis of Mesoporous TiO₂ in Ionic Liquids

Abstract:

The mesoporous TiO₂ particles was conveniently prepared in a room temperature ionic liquid (RTILs) of 1, 3-di-(3-propionyloxy) imdazolium tetrafluoroborate [DiprCOOBF₄ system. The obtained materials were characterized by powder X-ray diffraction (XRD), transmission electron microscopy (TEM), and N₂ adsorptiondesorption analysis. XRD patterns revealed that only rutile phase is formed in the RTILs. The TEM micrographs as well as N₂ adsorptiondesorption measurements show that the prepared products exhibited wormlike pore structures. The FTIR (Fourier Transform Infrared Spectra) demonstrate the carboxylate groups attach via bidentate or bridging coordination to the TiO₂ surface.
