Two new three-layer Aurivillius phases Bi2ASrTi2TaO12 (A=Bi, La) have been synthesized. The detailed structure determination of Bi2ASrTi2TaO12 (A=Bi, La) performed by powder X-ray diffraction (XRD) and selected area electron microscopy (SAED) shows that they all crystallize in the space group I/4mmm. UV–visible diffuse reflection spectrum of the prepared Bi2ASrTi2TaO12 (A=Bi, La) indicates that it had absorption in the ultraviolet (UV) region. The photocatalytic activity of the Bi2ASrTi2TaO12 (A=Bi, La) powders was evaluated by degradation of rhodamine B (RB) molecules in water under UV light irradiation. The results showed that Bi2ASrTi2TaO12 (A=Bi, La) has high photocatalytic activity at room temperature. Therefore, the preparation and properties studies of Bi2ASrTi2TaO12 (A=Bi, La) with a three-layer Aurivillius structure suggest potential future applications in photocatalysis.
Two new three-layer Aurivillius phases Bi2ASrTi2TaO12 (A=Bi, La) have been synthesized by a conventional solid state reaction method. And this is the crystal structure of the three-layer Aurivillius phases, Bi2ASrTi2TaO12.Figure optionsDownload as PowerPoint slide
