Abstract 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 ~0.6 μm. 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.
