Morphology of ZnO Controlled by Anion of Simple Zinc Salt
In this paper, three kinds of morphologies of ZnO crystals including particle-based lotus-like, hexagonal bipod-like (dumbbell-like) and rod-based chrysanthemum-like microstructures were controllably synthesized by using simple zinc salts (Zn(CH3COO)2·2H2O, ZnSO4·7H2O and Zn(NO3)2·6H2O) and ethanolamine as raw materials in microwave-assisted aqueous solution. The crystal structure, composition and morphology of the as-prepared products are characterized by X-ray diffraction (XRD), energy dispersive X-ray spectrometry(EDX), field-emission scanning electron microscopy(FESEM). It was found that anion of zinc salt is a dominative factor in determining the morphology of the obtained ZnO crystals. The possible formation mechanism of ZnO microstructures was simply discussed.
