Abstract
TiO2 spheres were synthesized on ZnO arrays with Al doped ZnO (AZO) glass substrate (named as AZT) by a two-step 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 μm, which increases first and then decreases with calcination temperature achieving a maximum at 450 °C. The sample calcined at 400 °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.
