Morphology and Photocatalytic Properties of γ-Bi2MoO6 
Tuned by Stirring and Surfactant EDTA Assistant
Visible light-driven photocatalyst γ-Bi2MoO6 was prepared by a hydrothermal process, with stirring in the preparation process, and surfactant ethylenediaminetetraacetic acid (EDTA) addition in precursors. The obtained samples were characterized by x-ray diffraction technique, scanning electron microscopy, technology electron microscopy, and ultraviolet–visible diffraction reflectance spectra. The obtained results suggest that the stirring and EDTA addition have one strong influence on the morphology. Meanwhile, the formation mechanism of γ-Bi2MoO6 with different morphologies was also discussed. The catalytic activation of γ-Bi2MoO6 photocatalysts was evaluated by methyl blue under visible light irradiation. It was found that the photocatalytic properties change largely with surfactant assistant.
