摘要：Fe doped ZnO nanoparticles with different Fe concentrations 0.5%-2% were synthesized by sol-gol route. X-ray diffraction (XRD) results revealed that the prepared nanoparticles presented the hexagonal wurtzite structure. No impure peaks were found. Scanning electron microscope (SEM) and transmission electron microscopy (TEM) confirmed the nanoparticle morphology of Fe doped ZnO. UV-vis spectrophotometer showed the high asorption both in UV and visible region. Photocatalytic activity was calculated by degrading methyl orange (MO) aqueous solution under solar light. ZnO with 0.5 at% Fe showed the highest photocatalytic performance. It was observed that MO dyes undergo 91% photodegradation under 4 h solar irradiation. The results show that the prepared Fe doped ZnO nanoparticles can be efffectively helpful for the photocatalytic applications.
