Effect of Erbium Ions Doping on the Properties and Photocatalytic Acitvity of Bi₁₂TiO₂₀

Abstract:

An erbium ion doped Bi₁₂TiO₂₀ was prepared by a simple method. XRD and UV-vis diffuse reflectance spectroscopy (DRS) were used to characterize the prepared photocatalysts. The results indicated that the erbium ion dopant had no influence on the phase of Bi₁₂TiO₂₀ and can extend its visible light adsorption spectra. Photocatalytic activities of the prepared samples were evaluated using methyl orange as a model organic compound. The results showed that doping with 0.5 mol% Er³⁺ can significantly improve the photocatalytic performance of Bi₁₂TiO₂₀.
