Electrospun Al2O3-TiO2 composite fibers were fabricated and characterized. Morphologies of the fibers after calcination at 500, 1000 and 1150°C, respectively, were examined by SEM, which showed that the diameters of the fibers decreased with increasing calcination temperature. XRD and TGA/DTA revealed that the Al2O3-TiO2 fibers consisted of α-Al2O3 and rutile TiO2 phases after calcination above 1150°C. FE-SEM images showed that the Al2O3-TiO2 composite was consisted of both small round particles and large block-like ones, which were assigned as α-Al2O3 and rutile TiO2 crystals, respectively. The Al2O3-TiO2 fibers displayed a photocatalytic reaction to decompose acetaldehyde under UV irradiation.
