摘要: ZnO doped with Cr, Mn, Fe, Co, Ni and Cu was prepared by homogeneous hydrolysis of sulfates urea. The samples were annealed at various temperatures characterized X-ray powder diffraction, UV/VIS reflectance spectroscopy, BET (Brunauer-Emmet-Teller) surface area porosity measurements. photocatalytic activity the evaluated measuring degradation an organic dye Reactive Black 5. morphology determined scanning electron microscopy atomic force microscopy. For Cu-doped sample, EPR spectra obtained. All 800°C contained hexagonal ZnO. In VIS region, best performance had Fe Cu.
