Ordered mesoporous titanium oxides were synthesized using a block copolymer as a structure-directing agent through N^0I^0 assembly pathway. The calcined mesoporous samples were characterized by TG-DTA, XRD, TEM and N~2 adsorption methods. These mesoporous oxides have inorganic framework and thick channel wall, in which small crystallites of anatase TiO~2 can be formed during calcination. The incorporation of Ce^3^+ ions into the channel wall dramatically improves the stability of the mesoporous structure.
