Facile synthesis of light harvesting semiconductor bismuth oxychloride nano photo-catalysts for efficient removal of hazardous organic pollutants
In the present work, bismuth oxychloride nanoparticles-a light harvesting semiconductor photocatalyst-were synthesized by a facile hydrolysis route, with sodium bismuthate and hydroxylammonium chloride as the precursor materials. The as-synthesized semiconductor photocatalysts were characterized using X-ray diffraction analysis, Fourier transform infra-red spectroscopy, Raman spectroscopy, Fiel...
متن کاملSynthesis and Photocatalytic Properties of BiOCl Nanowire Arrays
Bismuth oxychloride (BiOCl) nanowire arrays have been successfully prepared employing the Anodic Aluminum Oxide (AAO) template assisted sol-gel method. Nanowires of 100 nm diameter and length 26 μm, assembled in the porous of AAO templates, were formed. XRD and HRTEM results show that the nanowires are pure BiOCl polycrystal phase without Bi2O3 or BiCl3. The photocatalytic activity of BiOCl nan...

We demonstrate the first colloidal synthesis of single-crystalline BiOCl ultrathin nanosheets (UTNSs) that feature a well-defined square morphology. Unlike BiOCl nanomaterials prepared by hydrothermal routes, our colloidal BiOCl UTNSs exhibit hydrophobic surface properties and high activity and selectivity toward the photocatalytic aerobic oxidation of secondary amines to corresponding imines a...
متن کاملCitric acid modulated electrochemical synthesis and photocatalytic behavior of BiOCl nanoplates with exposed {001} facets.
Well-crystallized BiOCl nanoplates with exposed {001} facets were synthesized by a facile electrochemical anodic oxidation method. The thickness of the nanoplates decreases with increasing citric acid content in the electrolyte. The optical absorption edge of the BiOCl nanoplates shifts to a longer wavelength with citric acid. The BiOCl nanoplates obtained with citric acid show a high photocata...
متن کاملStudy of structural, electronic and optical properties of tungsten doped bismuth oxychloride by DFT calculations.
First-principle calculations have been carried out to investigate structural stabilities, electronic structures and optical properties of tungsten doped bismuth oxychloride (BiOCl). The structures of substitutional and interstitial tungsten, and in the form of WO6-ligand-doped BiOCl are examined. The substitutional and interstitial tungsten doping leads to discrete midgap states within the forb...
