Photocatalytic Mineralization of Methylene BlueAqueous Solutions by Ag/TiO2 Nano Composite

Nanocomposite of Ag/TiO2 and nanocrystalline TiO2 were prepared by using TiCl4 as a precursor in a simple sol-gel process. The prepared photo-catalysts were characterized by X-ray diffraction (XRD), scanning electron micrographs (SEM), energy dispersive X-ray microanalysis (EDX), transmission electron microscopy (TEM) and diffuse reflectance spectroscopy (DRS). A complete and effective photocat...

Removal of methylene blue dye by application of polyaniline nano composite from aqueous solutions

This paper deals with application of polyaniline coated on wood sawdust for removal ofmethylene blue (MB) dye from aqueous solutions. Polyaniline coated onto sawdust (termedas PAn/SD) was prepared via direct chemical polymerization onto sawdust which waspreviously soaked in the monomer (aniline) solution in acidic (HC1) media. Adsorptionexperiments were carried out using batch system. The effec...

Photocatalytic discoloration of the azo dye methylene blue in the presence of irradiated TiO2/Pt nano-composite

An efficient photocatalytic material TiO2/Pt was prepared via the sonochemical synthesis followed by the thermal treatment. The TiO2/Pt nanocomposite was able to photocatalytically degrade the azo dye methylene blue (MB) under UV (ultraviolet) and Vis (visible) irradiation. The enhanced photocatalytic activity of Pt/TiO2 for methylene blue degradation is attributed to the following factors; to ...

Photocatalytic Degradation of Methylene Blue by Innovative BiVO4/TiO2 Composite Films under Visible Light Irradiation

Bismuth vanadate and titanium dioxide (BiVO4/TiO2) composites, used as visible-light-driven photocatalysts were successfully synthesized with different mole ratios by coupling of a co-precipitation method with a sol-gel method. The phase transitions of the as-prepared BiVO4/TiO2 composites were carried out by X-ray diffraction (XRD). The results clearly indicated that the as-synthesized BiVO4/T...
