چکیده انگلیسی
ZnO nanocages and other nanostructures have been synthesized via a simple one-pot hydrothermal method with different reaction times. It is worth mentioning that this is a completely green method which does not require any other chemicals except that Zn foil served as Zn source in the experiment. X-ray diffraction (XRD), Scanning electron microscopy (SEM), transmission electron microscopy (TEM), photoluminescence (PL) and UV-Vis diffuse reflection spectra were used to characterize the crystallinity, morphology and optical property of ZnO structures. Growth mechanisms of ZnO were proposed based on these results. Furthermore, ZnO films with different morphologies and crystal growth habits exhibited different activities to rhodamine B degradation. The influence of the reaction time on the morphology of ZnO films and the effect of the morphologies on the photocatalytic activity are discussed.
