The present work deals with the crystallization of monolithic TiO2 aerogels in environment of pure and water modified scCO2. To remove organic precursors used during sol-gel synthesis and to crystallize TiO2 the combination of several steps with pure and watermodified scCO2 was tested with respect the high porosity and the specific surface area of titania blocks.
