Abstract
Disk- and filament-like ZnO crystals were decorated on one-dimensional TiO(2) nanostructures (TiO(2)-ZnO) through various integrated physical and chemical synthesis methods. The morphology of the ZnO crystals on TiO(2) varied with the chemical synthesis method used. ZnO nanodisks decorated with TiO(2) nanorods (TiO(2)-ZnO-C) were synthesized using the chemical bath deposition method, and ZnO filament-like crystals decorated with TiO(2) nanorods (TiO(2)-ZnO-H) were synthesized through the hydrothermal method. Compared with the pristine TiO(2) nanorods, the as-synthesized TiO(2)-ZnO composites exhibited enhanced photophysiochemical performance. Furthermore, because of their fast electron transportation and abundant surface active sites, the ZnO nanodisks in the TiO(2)-ZnO-C composite exhibited a higher photoactivity than those in the TiO(2)-ZnO-H composite. The morphology and crystal quality of the ZnO decoration layer were manipulated using different synthesis methods to realize disk- or filament-like ZnO-decorated TiO(2) composites with various photoactive performance levels.
