Fabrication and Photocatalytic Properties of Nanosheet-Based ZnO Hierarchical Microflowers

Nanosheet-based ZnO hierarchical microflowers were synthesized using a facile one-pot hydrothermal approach. Analytical methods such as X-ray diffraction, scanning electron microscopy, transmission electron microscopy, selected area electron diffraction, and high-resolution transmission electron microscopy were employed to characterize these products, and photocatalytic properties of ZnO hierarchical microflowers were also investigated. Nanosheet-based ZnO hierarchical microflowers exhibited enhanced photocatalytic properties as compared with irregular ZnO nanosheets and nanorods. Investigations confirmed that hierarchical structures had a pronounced influence upon the photocatalytic properties of ZnO.
