 A novel method was developed to create a ZnO seed layer with a protruding matrix structure, which allowed for the easy formation of ZnO nanorata rays, ZnO NFAs. This seed layer was then transferred onto a silicon substrate using a lift-off process, allowing for vertical growth of ZnO NFA structures. As the growth time increased, the diffraction peaks of the five growth directions of ZnO NFAs increased, while the length, width, aspect ratio, and total surface area of ZnO NFAs also increased. Additionally, the effect of ZnO NFAs on methylene blue degradation was enhanced with increasing synthesis time. This article was authored by XIN Zhao, Qingshan Wang, NNICHO, and others.
