Abstract: ZnO nanostructure were synthesized via microwave
method using zinc acetate as starting material, guanidinium as
structure directing agents, and water as solvent.. This work
investigates the photodegradation of azo dyes using the ZnO Flowerlike
in aqueous solutions. As synthesized ZnO samples were
characterized using X-Ray powder diffraction (XRD), scanning
electron microscopy (SEM), and FTIR spectroscopy.In this work
photodecolorization of congored azo dye under UV irradiation by
nano ZnO was studied.
