Article Preview

In this study, titania powders were prepared from 0.02M titanium tetrachloride and 0.08M sodium hydroxide in a high gravity rotary reactor. The preparation was combined with a precipitation, washing/centrifugation, hydrothermal and drying steps. The prepared titania powders were characterized by TGA, SEM, TEM, FTIR, and UV-vis analysis。TGA curves show that the titania yield was found to increase with rising hydrothermal time. TEM analysis show that the prepared titania crystalline in solution has a flake-like shape with a primary size 5~15nm and narrow size distribution. SEM images show that the primary titania crystalline aggregates to large secondary powders with a size 5~20μm。FTIR and UV-vis spectra show that the prepared precursor is titanium hydroxide that was transferred into titanium dioxide after hydrothermal process under a suitable temperature and time.
