Abstract

Abstract:

As an important Ⅱ-Ⅵ semiconductor, ZnO possesses a band gap around 3.37 eV and shows huge potential applications in optoelectronics, sensing, photocatalysis, electricity generation and so on. In this work, we successfully synthesized Fe doped ZnO hollow microspheres via simple ion exchange and thermal evaporation methods. The morphology, structure and composition of the product have been systematically investigated using scanning electron microscope (SEM), transmission electron microscope (TEM) and X-ray diffraction (XRD). Light absorption measurements indicated that Fe dopants can enhance the light absorption performance of ZnO in light wave band of 375~600 nm. Additionally, photocatalytic characterization demonstrated that Fe doped ZnO hollow microspheres can promote the photodegradation of Rhodamine B, implying that the as-synthesized Fe doped ZnO hollow microspheres are extraordinary photocatalysis.

Key words: thermal evaporation, ZnO, Fe dopants, hollow microspheres, photocatalysis
