Název v původním jazyce

Functional and eco-friendly nanocomposite kaolinite/ZnO with high photocatalytic activity

Popis výsledku v původním jazyce

Highly photoactive nanocomposites kaolinite/ZnO with various amounts of ZnO nanoparticles (10 wt.%,30 wt.%, and 50 wt.%) were prepared using simple hydrothermal method. Calcination of the nanocomposites at 600oC led to the kaolinite-metakaolinite phase transformation, to further growth of ZnO crystallites, and to significant increase of photodegradation activity. The nanocomposites were studied using X-ray fluorescence spectroscopy, X-ray powder diffraction, Fourier transform infrared, diffuse reflectance and photoluminiscence spectroscopies, scanning and transmission electron microscopies, BETanalysis, and molecular modeling using empirical force field. Photodegradation activity was evaluated bythe discoloration of Acid Orange 7 aqueous solution underUV irradiation. Leaching tests confirmed strong interaction between kaolinite matrix and ZnO nanoparticles, and, therefore, high stability of prepared nanocomposites.
