| Abstract: | Based on the two dimensional nanometer-reactor properties of interlayer spacing of montmoril-lonite,tetrabutyl titanate was introduced into the interlayer spacing of organic montmorillonite by solvent process.TiO2 was formed by using the interlayer spacing of montmorillonite as the reaction space.X-ray diffraction(XRD),in situ temperature Raman spectroscopy and TEM were used to analyze the reaction and hydrolyzation process of tetrabutyl titanate,the process of nucleation and structural phase transition of ... |
