ZnO nanorods were successfully fabricated by a simple chemical reaction from zinc chloride (ZnCl2) and sodium hydroxide (NaOH) in 3 h refluxing at 60 °C and 80 °C. The crystallinity of the grown products was analyzed by X-ray diffraction technique revealing the as prepared ZnO samples have hexagonal wurtzite structure. Their morphology was investigated by using TEM, which showed that nanorods of 25 nm (80 °C) – 30 nm (60 °C) in average diameter had been formed. The photocatalytic property of ZnO nanoparticles were investigated via methyl orange as a model organic compound under UV light irradiation.
