Abstract: Aurivillius compound Bi7Ti4NbO21 was fabricated by a chemical solution decomposition method(CSD)and acid treated. X-ray diffraction(XRD)analysis revealed that well-crystallized Bi7Ti4NbO21 could be prepared with a calcination temperature at or above 550 ℃. Well-crystallized Bi2Ti2O7 with uniform particle sizes was obtained by concentrated nitric acid treatment. Field emission scanning electron microscopy(FESEM)was used to examine the morphology and particles size of as-prepared Bi7Ti4NbO21 and acid-treated product Bi2Ti2O7. The results showed that both Bi7Ti4NbO21 and Bi2Ti2O7 were highly photocatalytic active for the degradation of organic dye methyl orange under UV light irradiation. The crystallinity and particles size of as-prepared photocatalysts were found to strongly influence the photocatalytic activities. The BTN-550 calcined at 550 ℃ showed the highest activity of as-prepared Bi7Ti4NbO21. The Bi2Ti2O7 obtained by acid-treated Bi7Ti4NbO21 exhibited remarkable enhanced photocatalytic activity which was superior to that of P25.

Key words: acid treatment, photocatalytic, degradation, Bi2Ti2O7, Bi7Ti4NbO21
