Highly improved photocatalytic degradation of rhodamine B over Bi₂Ga_4-x Fe _x O₉ solid solutions under visible light irradiation.

ABSTRACT: In this work, Bi₂Ga_4-x Fe _x O₉ (0 ≤ x ≤ 1.2) solid solutions were prepared via the traditional high-temperature solid-state reaction. The Le Bail fitting on the powder X-ray diffraction patterns shows that these solid solutions were successfully synthesized. Scanning electron microscopy showed that the Bi₂Ga_3.2Fe_0.8O₉ sample was composed of sub-micron particle crystallites. Energy dispersive spectroscopy analysis and X-ray photoelectron spectroscopy were used to identify that the Fe element is trivalent when doping into the crystal structure. Ultraviolet-visible diffused reflectance spectra suggested that the bandgap of Bi₂Ga_3.2Fe_0.8O₉
