摘要：

TiO2 spheres were synthesized on ZnO arrays with Al doped ZnO (AZO) glass substrate (named as AZT) by a twostep method. XRD, SEM, EDS, TEM, and UV-Vis were used to explore the effect of calcination temperature on the crystal structure, morphology, composition and photocatalytic performance of AZT samples. Results indicate that the calcination temperature has a vital role in forming different morphologies of TiO2 including flake-like, block, spheres, and aggregates. The diameter of TiO2 spheres is in the range of 0.5-3.5 mu m, which increases first and then decreases with calcination temperature achieving a maximum at 450 degrees C. The sample calcined at 400 degrees C shows the most excellent photocatalytic degradation performance of methyl orange under 15 W weak-ultraviolet light irradiation, which is mainly due to the moderate particle size, high dispersibility and well crystallinity of TiO2 spheres.
