摘要
Zinc oxide nanoparticles were synthesized by the reaction of an aqueous-alcoholic solution containing zinc nitrate hexahydrate and sodium hydroxide under ultrasonic irradiation at room temperature. The crystallinity, morphology and optical property of ZnO-nanoparticles were examined by X-ray diffraction, scanning electron microscopy, transmission-electron microscopy and UV-visible spectrophotometer. Zinc,oxide nanoparticles multilayer films were prepared dipping glass slide, which had been cleaned with a piranha ablution, into a ZnO solution by ultrasonic irradiation. The ZnO nanoparticles multilayer films were evaluated as a photocatalyst in the photocatalytic degradation of organic dyes, such as methylene blue, methyl orange and rhodamine B, under ultraviolet light at 254 nm.
