摘要：

Ordered mesoporous titanium oxides were synthesized using a block copolymer as a structure directing agent through (NIo)-I-o 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 TiO2 can be formed during calcination. The incorporation of Ce3+ ions into the channel wall dramatically improves the stability of the mesoporous structure.
