Název v původním jazyce

Photocatalytic behavior of nanosized TiO2 immobilized on layered double hydroxides by delamination/restacking process

Popis výsledku v původním jazyce

Efficient immobilization of TiO2 nanoparticles on the surface of Mg2Al- LDH nanosheets was performed by delamination/restacking process. The structural and textural properties of as-prepared nanocomposites were deeply analyzed using different solid-statecharacterization techniques such as : X-ray powder diffraction, FTIR and Raman spectroscopies, chemical analysis, X-ray photoelecton spectroscopy, N2 adsoprtion-desorption and electronic microscopy. The photocatalytic properties of immobilized TiO2 nanoparticles on Mg2Al were investigated using the photodegradation of two model pollutants : Orange II and 4-chlorophenol, and compared with pure colloidal TiO2 solution. It appears that Orange II photodegradation was systematically faster and more efficient than 4-chlorophenol photodegradation regardless of the medium pH. Moreover under slightly basic conditions, even if the TiO2 photocatalytic efficiency decreases, photodegradation performed in presence of easily recovered TiO2/Mg2Al1.5 n
