| Abstract: | A bi-crystalline TiO2 consisting of monocline and anatase was synthesized through the hydrothermal reaction of tetrabutyl titanate and sodium hydroxide with butyl end-capped fatty alcohol ethoxylates as phase regulator. The effects of phase regulator, hydrothermal reaction temperature and time on the crystalline phase of the products were investigated, and the phase transformation mechanism was preliminarily discussed. |
