In this study, we prepare the zinc oxide one-dimensional nanostructures with aqueous solution on GaN substrate. The morphologies of nanotip, nanorod and nanotube are formed with different modulation and chemical solutions. The thermal annealing with N2O ambiance at 300 ¢XC for 1 hr increase the UV emission and decrease the defects. The limit of choosing the substrate to grow ZnO nanostructures is lattice mismatch between ZnO and substrate. The buffer layer is sputtered on substrate to remove the limit. The pattern of buffer layer also can be used for selective area growth. Nanotip structure with rough surface shows the obvious lotus effect and nanotube structure with more active site and more surface area shows the better photocatalysis efficiency than nanotip structure.
