Fabrication and Morphological Control of Hierarchical-structure ZnO†

doi:10.7503/cjcu20140083

Abstract

Abstract:

The hierarchical-structure ZnO with different morphologies were fabricated by the hydrothermal method respectively using single and mixed zinc salts as the zinc source, sodium hydroxide as the precipitant, alanine and ionic liquid(IL) as the surfactant. The samples were characterized by XRD analysis, SEM observation, IR and UV-Vis spectrometry. The influential factors of the sample morphology were discussed, which included the zinc source(single, double and three zinc salts), the kind and dosage of ionic liquid, the dosage of alanine and temperature, etc. The modulation of anionic on sample morphology was speculated in the formation process of the ZnO with hierarchical structure.
