摘要：
Li8Bi2(MoO4)(7) was synthesized by a one-step combustion method. The structure, morphology, adsorbance, optical and photocatalytic properties of as-obtained sample were studied by X-ray powder diffraction, scanning electron microscopy, ultraviolet-visible spectrophotometry. The experimental results show that the formation of tetragonal Li8Bi2(MoO4)(7) was one-pot achieved. The sample exhibits a irregular particle morphology with an average size of similar to 0.6 mu m. The direct energy band gap calculated from the diffuse reflectance spectrum is 3.25 eV. Compared with TiO2 (P25), as-synthesized Li8Bi2 (MoO4)(7) shows better visible light photodegradation performance for MB, which can be attributed to its excellent adsorbability.
