Nano-crystalline ZnO particles were synthesized by a reactive ion exchange procedure using ZnSO 4 and NaOH as precursors and a strong basic anion exchange resin as substrate. The precursors and ZnO samples were characterized by scanning electron microscopy, X-ray diffraction, and UV-Vis spectroscopy. The ZnO particles were club shape, and the synthesis process depended on the reactant concentration...
