ZnO was prepared via hydrothermal synthesis rout by using Zn（CH3COO）2·2H2O and NaOH as reactants and dextrin as morphology controller agent at the temperature of 120 ℃.The prepared sample was characterized by X-ray powder diffraction,scanning electron microscopy,transmission electron microscopy and High-resolution transmission electron microscopy,respectively.Results indicated that the synthesized sample was hexagonal wurtzite ZnO phase,and was composed by many flower-like hierarchical nanostructured ZnO particles.The synthesized flower-like hierarchical nanostructure was assembled by many flake-like naoparticles with the mean thickness of about 50 nm,and owned good photocatalytic property.
