Alumina–titania ceramic membrane with mesopore and narrow pore size distribution was prepared by the sol–gel
process. Observations were based on membrane weight loss, morphology, pore size distribution and BET surface
area. Thermogravimetric analysis (TGA), Scanning Electron Microscopy (SEM) and N2 adsorption-desorption analysis
were employed for the membrane characterization. TGA curve shows that the suitable temperature for calcination of
alumina-titania membrane is at 600°C. The SEM morphology displays a smooth and free-crack layer of alumina-titania
membrane after calcination at temperature of 600°C. Furthermore, the membrane was also successfully coated with a
good adhesion to complement with support. The thickness of the membrane layer was estimated at 4 μm. N2
adsorption-desorption confirms the existence of a mesoporous structure for membrane as BET surface area and
average pore size of the membrane layer were 292 m2g-1 and 1.8 nm respectively.
