Notes:
By the usage of the hydrolysis of Ti alkoxide, various types of TiO2 were obtained throughthe addition of catalyst (HCl, NH4OH, and CH3COONH4) and some additives into Ti alkoxidesolution at room temperature. In special, the effect of two additives, diethylene glycol (DEG) andhexamethylphospheric triamide (HMPA), on hydrolysis behaviors and microstructure with variouscatalyst for hydrolysis of Ti-tetraisopropoxide was in detail investigated. In case of TiO2 powder withHMPA as an additive, the crystallinity of TiO2 except with NH4OH as a catalyst decreased in XRDpatterns, compared to those of products with no additive and with DEG as an additive. The additionof HMPA prohibited the growth of TiO2 and led to fine TiO2 with the average particle size ofapproximately 10nm
