Hydrothermal Synthesis and Photocatalytic Property of Flower-Like ZnO Hierarchical Microstructures

Article Preview

Abstract:

ZnO hierarchical microstructures with uniform flower-like morphology were successfully prepared on a large scale through a carboxymethylcellulose sodium (CMC)-assisted hydrothermal route. X-ray powder diffraction (XRD) measurement confirmed the formation of wurtzite-structured ZnO phase. Field-emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) analysis indicated that the as-prepared ZnO sample was composed of numerous three dimensional flower-like microstructures, each of which was assembled by nanosheets with the thickness of about 40 nm. High-resolution transmission electron microscopy (HRTEM) measurement revealed the good crystallinity nature of the ZnO nanosheets in the flower-like microstructures. The formation mechanism and photocatalytic property of the as-prepared flower-like ZnO hierarchical microstructures were studied.
