Visible light-driven photocatalyst gamma-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 gamma-Bi2MoO6 with different morphologies was also discussed. The catalytic activation of gamma-Bi2MoO6 photocatalysts was evaluated by methyl blue under visible light irradiation. It was found that the photocatalytic properties change largely with surfactant assistant.
