| Abstract: | Mesoporous TiO2 anatase was synthesized by hydrothermal method,using industrial H2TiO3 as raw material.The effect of hydrothermal temperature and time on the crystal size of TiO2 was investigated,and TiO2 was characterized by N2 adsorption-desorption isotherm,SEM and TG-DTA.The results showed that the crystal size of TiO2 was heavily dependent of the hydrothermal temperature,but slightly relevant to the hydrothermal time.Micron mesoporous TiO2 with an average pore diameter of 8.8 nm and high thermal stabili... |
