In the present paper, the preparation and characterization of porous alumina-titania nanostructure membrane is described. The membrane layers consisted of an α-alumina membrane support which was dip-coated with a composite alumina-titania top layer prepared in a sol-gel process. Thermogravimetric analysis showed that drying progress of the membrane layer is completed at about 560 °C. Scanning electron microscopy analysis displayed a smooth and defect-free layer of alumina-titania membrane after calcination at 600°C. X-Ray diffraction analysis showed the formation of Gamma and orthorhombic alumina, brookite titania, and aluminium titanate (Al2TiO5) after the calcination step. Transmission electron microscopy analysis showed that the alumina-titania composite particle size was almost below 40 nm. The Brunauer–Emmet–Teller (BET) surface area, average pore size and thickness of the membrane top layer were determined 292 m2/g, 2.2 nm and 4 µm, respectively.
