A visible light driven doped TiO2 nanophotocatalyst: Preparation and characterization
A useful nanophotocatalyst (La,S-TiO2) was prepared by a sol-gel method and characterized by UV–vis diffuse reflectance spectroscopy (DRS), X-ray diffraction (XRD), photoluminescence emission spectroscopy (PL) and scanning electron microscopy (FESEM). The results showed that the La,S-TiO2, which calcined at 550 °C, contained only anatase phaseand its crystal size was 23 nm...

متن کاملSynthesis and characterization of Lanthanum doped Bismuth Ferrite
B1-xLaxFeO3 (x = 0.0, 0.025) crystallites were prepared by chemical solution route. XRD analysis confirmed the phase formation of the materials. Thermal characterization was done by DSC-TGA to confirm crystallization and thermal behavior for phase development. Morphological studies by FESEM showed the agglomerated nature of the ferrite...

متن کاملEnhanced Visible Light Photocatalytic Activity of Br-Doped Bismuth Oxide Formate Nanosheets.
A facile method was developed to enhance the visible light photocatalytic activity of bismuth oxide formate (BiOCOOH) nanosheets via Br-doping. The as-prepared samples were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, the Brunauer-Emmett-Teller surface area, UV-vis diffuse reflectance spectroscopy, photolum...
