Abstract Mesoporous titania was preparated by alcohol-heating method using cetyltrimethyl ammonium bromide(CTAB) as a template,tetra-n-butyl titanate(TBOT) as titanium source and anhydrous ethanol as a solvent. The products were characterized by N2 adsorption-desorption, XRD and TEM . The catalytic activity of mesoporous titania was investigated by the photocatalytic degradation of methylene blue and compared with Degussa P–25. The results show that the anatase TiO2 powder with the specific surface area of 248.8 m2/g, and a pore radius of 4.92 nm, has better photocatalytic activity.

Key words: nanopowder mesoporous TiO2 alcohthermal method photocatlysis
