ZnO/Bi2O3 nanowire composites as a new family of photocatalysts
Popis výsledku v původním jazyce
Zinc?bismuth oxide?peroxide (ZnO* ZnO2 * Bi2O3) nanorod-like particles were prepared for photocatalytic application by the thermal hydrolysis of a zinc?peroxyl-complex precursor. Bi3 + doping has a strong effect on the morphological structure of the resulting product: lower Bi3 + concentrations preferentially form nanorods, whereas higher Bi3 + concentrations preferentially form a flower-like morphology. The synthesised samples of zinc?bismuth oxide?peroxides were examined by X-ray diffraction, Raman spectroscopy, UV?Vis diffuse reflectance spectroscopy, scanning electron microscopy and nitrogen adsorption?desorption isotherm analysis. Electron spin resonance (ESR) was used to monitor the hydroxyl radicals HO* radical dot on the zinc surfaces. The photocatalytic activity of the prepared samples was determined under the photocatalytic decomposition of Orange II dye in an aqueous slurry under UV or visible light irradiation. The best photocatalytic activity was achieved for the sample de
