Photocatalytic decolorization of methyl orange dye using nano-photocatalysts
Environmental contamination, which is growing around the world, is a serious problem can not to be neglected. Among all contaminations, water pollution is a major problem. Azo dyes are one of the largest groups of pollutants found in the drinking water, coming from, and the food and textile industries. TiO2/Fe3O4 and TiO2/Fe2O3 nanocomposites with various ratios were synthesized by an ultrasoni...

متن کاملComposition and Structure Evolution of Bi2O3 Coatings as Efficient Photocatalysts
To overcome the recovery disadvantages of Bi2O3 photocatalyst in the form of powder, Bi2O3 photocatalyst coatings were developed via a ball milling, followed by the calcination method. The composition and structure evolution rules of the as-synthesized samples were analyzed based on XRD (X-ray powder diffraction) patterns and SEM (scanning electron microscope) observations. XPS (X-ray photoelec...
متن کاملSynthesis of ZnO/Bi2O3 and SnO2/Bi2O3/Bi2O4 mixed oxides and their photocatalytic activity
In the present work, ZnO/Bi2O3, SnO2/Bi2O3/Bi2O4 mixed oxide, Bi2O3 rod-like and SnO2 nanoparticle have been synthesized. The obtained samples were characterized by field emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD). The optical properties of samples were evaluated by UV-Vis spectrophotometer. The photocatalytic activity of samples was evaluated by decolorization o...
متن کاملVisible light mediated photocatalytic activity of cobalt doped Bi2O3 nanoparticles
Herein, we suggest a novel chemical precipitation method to prepare different concentrations (0.05–0.25 M) of cobalt doped Bi2O3 nanoparticles. The prepared products exhibit excellent structural and optical properties. The influence of doping on the morphology of Bi2O3 was analyzed by FE-SEM and confirmed by HR-TEM. Furthermore, the photocatalytic activities of the samples were studied in the d...
