文摘

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.
