Abstract: Bi3OXy(WO6)1-y (X=Cl, Br, I) solid solution materials were successfully prepared by a simple two-step hydrothermal method, which enhanced the adsorption and photocatalytic properties while changing the morphology. The structures and properties of the three composites were characterized in detail by X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet-visible diffuse reflection spectroscopy (UV-Vis DRS), X-ray photoelectron spectroscopy (XPS), and photoluminescence spectroscopy (PL). Solid solutions were speculated in principle. Compared to the BW monomer, the formation of the BI solid solution in Bi3OXy((WO6)1-y resulted in a decreased band-gap, which led to an enhanced capacity for absorbing visible light. Furthermore, it helped to reduce the recombination rate of electron-hole pairs generated by light. Bi3OXy((WO6)1-y exhibited a strong adsorption capacity for rhodamine B (RhB) cationic dye. Adsorption kinetics of different materials were investigated through adsorption experiments conducted at high concentrations. |
