Abstract

ZnO micro-flowers composed of hexagonal nanorods were successfully fabricated by soft chemical technique from zinc acetate di-hydrate (Zn(CH₃COO)₂·2H₂O) and sodium hydroxide (NaOH) in 1h refluxing. The crystallinity of the grown product was analyzed by X-ray diffraction technique revealing the as-prepared micro-flowers have hexagonal wurzite structure. Their morphology was investigated by using FESEM and TEM, which showed that well-dispersed micro-flowers of 2-3μm in diameter had been formed. Furthermore, the synthesized micro-flowers showed a better photo-catalytic activity in presence of methylene blue (MB) dye. Also, the Zn_2p1/2, Zn_2p3/2, and O_1s peaks in X-ray photoelectron spectroscopy clearly suggest that the grown nanostructures are pure ZnO. Additionally, high performance liquid chromatography (HPLC) and liquid chromatography-mass spectroscopy (LC-MS) were applied to observe the degradated compounds from the photo-catalytic degradation of methylene blue (MB) dye in presence of zinc oxide micro-flowers.
