Structural and photochemical properties of Fe-doped ZrO2 and their application as photocatalysts with TiO2 for chromate reduction

In this work, we are interested by the photocatalytic activity under sunlight irradiation of Fe-doped ZrO2 prepared by co-precipitation. The structural and photophysical properties of the catalysts have been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), BET method and UV–Vis diffuse reflectance. The results show that Fe-doped ZrO2 exhibits higher photocatalytic activity than...
