Super/subcritical fluid extractions for preparation of the crystalline titania

Abstract

Various extraction techniques which use fluids in super/subcritical state (CO2, H2O, CH3OH) were used for the preparation of crystalline TiO2 from surfactant-mediated titania organogels (the amorphous reaction intermediate products of surfactant-mediated sol–gel synthesis).
