Description

Highlights: → Zn1-xFexO nanocrystallines are prepared by precipitation method, and characterized by X-ray powder diffraction (XRD) and UV-vis diffuses reflectance spectroscopy. → Zn1-xFexO nanocrystallines show high photocatalytic activities for xanthate degradation at pH 7 under visible light irradiation. → Zn0.96Fe0.04O nanocrystallines exhibit the highest photocatalytic efficiency, which is attributed to the balance between visible light absorption and valence band edge potential. - Abstract: Zn1-xFexO nanocrystallines are prepared by precipitation method, and characterized by X-ray powder diffraction (XRD), Transmission electron microscopy (TEM), and UV-vis diffuses reflectance spectroscopy. Zn1-xFexO nanocrystallines show high photocatalytic activities for xanthate degradation at pH 7 under visible light irradiation. Zn0.96Fe0.04O nanocrystallines exhibit the highest photocatalytic efficiency, which is attributed to the balance between visible light absorption and valence band edge potential.
