Summary: The morphological properties of ZnO nanostructures such as nanorods, nanowires, and nanotubes can significantly affect their photocatalytic performance. In this study, the physical properties (optical and shape) of different 1-D ZnO nanostructures were evaluated in relation to their photocatalytic efficiency. ZnO nanorods transformed into nanowires under reduced seeding precursor concentration and into nanotubes with prolonged incubation time. The highest photocatalytic efficiency was observed in ZnO nanotubes, followed by ZnO nanowires and nanorods. The enhanced efficiency of ZnO nanotubes was attributed to their large polar face, high UV absorption, and large photocurrent density.
