Preparation and characterization of TiO2 photocatalysts by Fe3+ doping togeth…

Abstract. Fe3+ doped TiO2 deposited with Au (Au/Fe–TiO2) was successfully prepared with an attempt to extend light absorption of TiO2 into the visible region and reduce the rapid recombination of electrons and holes. The samples were characterized by X-ray diffraction (XRD), N2 physical adsorption, Raman spectroscopy, atomic absorption flame emission spectroscopy (AAS), UV–vis diffuse r…
