نویسندگان
چکیده
The four-layered Aurivillius SrBi4Ti4O15 compound has been reported to be potentially used as a photocatalyst material. In this research, was prepared by the molten salt method using NaCl/KCl and then degrade methylene blue. analysis of sample diffractogram indicated that obtained but there still impurities Bi4Ti3O12. micrograph showed particle shape is plate-like (sheets) with lot agglomeration. band gap energy 3.14 eV (394.85 nm), according Kubelka-Munk calculation from spectrum reflectance. photocatalytic test results degraded blue 47.8% in 120 minutes.

متن کاملNi/Ti layered double hydroxide: synthesis, characterization and application as a photocatalyst for visible light degradation of aqueous methylene blue.
Visible light responsive 2 : 1 Ni/Ti layered double hydroxide (LDH) was synthesized by a single step hydrothermal route using commercially available Ni(NO3)2·6H2O, TiCl4 and urea. The material exhibited significant absorption in the visible range with a very narrow band gap (2.68 eV). This could be attributed to structural defects as confirmed by diffuse reflectance spectroscopy (DRS), photolum...
