Paper Title:
Preparation of Titania with Different Morphologies
  Abstract

In this study, the commercial titanium dioxide (P25) was used to prepare titania aggregates with different morphologies The preparation procedure included the alkali treatment, hydrothermal with different reaction temperature and time, and sequentially spray drying. The results show that the hydrothermal temperature and time have a great influence on the morphology of primary titania particles. The results show that the one-dimensional nanotube, nanorod, and nanowire titania are obtained at T=140°C for t=24h, T=180°C for t=24h, and T=180°C for t=72h, respectively. Moreover, the obtained titania with different primary shapes are successfully applied to prepare the titania secondary particles with various morphologies, i.e., ring-like net structure, bird nest-like porous structure, and dense spherical structure. The optical absorption spectra also show that the titania aggregates obtained after spray drying have a higher optical absorbance in a range of ultraviolet and visible regions.
