摘要：Ag-doped MgBi₂O₆ photocatalysts were synthesized by the low temperature hydrothermal method in combination with heat treatment reaction using NaBiO₃ 2H₂O, MgCl₂ 6H₂O, and AgNO₃ as raw materials. The products were characterized by using power X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), Energy dispersive X-ray detector (EDS), and UV-Vis diffusion reflectance spectra. The photocatalytic activity of MgBi₂O₆ with Ag additions was evaluated by degrading MB (10 mg/L) under visible light irradiation (λ > 420 nm). The results showed that in comparison with pure MgBi₂O₆, the photocatalytic activity of MgBi₂O₆ with about 5% Ag concentration is increased by about 24% after 120 min reaction. The enhancement of catalytic activity of Ag-doped MgBi₂O₆ photocatalysts should be related to the band structure, morphology and larger specific surface area.
