We report the successful preparation of flower-like ZnO microstructures in one step by a simple, rapid and reliable ultrasound irradiation route, using only Zn(CH3COO)(2) and NaOH as starting materials. The product was characterized by powder X-ray diffraction, energy-dispersive X-ray spectrometry, transmission electron microscopy and scanning electron microscopy. The UV-vis absorption and emission spectra, photocatalytic activity and electrochemical properties of the as-obtained flower-like ZnO microstructures were studied. (C) 2008 Acta Materialia Inc.
