ABSTRACT:
Essentially mesoporous titanium oxide materials, having an average pore diameter of no more than about 100 .ANG. (e.g., from about 20 .ANG. to about 50 .ANG.) and an average surface area of no less than about 300 m.sup.2 /gm, preferably no less than about 500 m.sup.2 /gm are disclosed which optionally can contain an effective amount of at least one transition metal (e.g., a rare earth metal, iron, or the like) for stabilization. These materials can be formed by treating a titanium source, which is derived from a titanium alkoxide, in an organic-aqueous solution, with an organic structure directing agent (e.g., higher alkyl amine, optionally in the presence of an alcohol cosolvent) to form meso-sized micelles and hydrothermally treating the resulting composition.
