A facile mixed-solvothermal route to γ-Bi2MoO6 nanoflakes and their visible-light-responsive photocatalytic activity

γ-Bi2MoO6 nanoflakes were successfully synthesized by a mixed-solvothermal process with SDBS involved in the reaction. The as-prepared γ-Bi2MoO6 was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and UV–vis absorption spectroscopy. The effect of different ratio of solvents on the resulting products was investigated. The visible-light-responsive photocatalytic activities of the obtained γ-Bi2MoO6 nanoflakes were evaluated by photodegradation of Rhodamie B under visible light (λ > 400 nm). The high degradation efficiency of RhB was attributed to the good crystallization and flake-like morphology of γ-Bi2MoO6 nanostructures, which is in accord with the photocurrent result.
