In this work, pomegranate juice was used as capping agent for self-assembly to form rod-like ZnO nanostructures in the presence of Zn(NO3)2·3H2O as zinc source. Besides, to investigate the concentration effect of pomegranate juice as the green capping agent on the morphology and particle size of final products several experiment were performed. The as-synthesized products were characterized by X-ray diffraction, energy dispersive X-ray spectroscopy, scanning electron microscope, transmission electron microscope, Fourier transformation infrared, and photoluminescence spectroscopies. Moreover, the efficiency of ZnO nanostructures as a photocatalyst for the decolorization of methylene blue using visible light irradiation has been evaluated. Furthermore, the photocatalysis results reveal that the maximum decolorization of 95 % in 60 min under ultraviolet light irradiation.
