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(CH 3 COO) 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...
In the present work, we report the successful preparation of columnar hexagonal-shaped ZnO crystals in one step by a simple, rapid and reliable microwave irradiation route, using Zn(CH 3 COO) 2 , hexamethylenetetramine, acrylamide and 2,2′-azo-bis-iso-butyronitrile as the starting materials. The in situ produced polyacrylamide acted as the surfactant directing the growth of ZnO crystals...
