Název v původním jazyce

Tailoring photocatalytic activity of TiO2 nanosheets by Fe-57

Popis výsledku v původním jazyce

TiO2 nanosheets were modified by two different procedures (volume and surface modification) with 0.5 wt % of 57Fe toward Ti. In the case of volume modification, the 57Fe (in the form of 57Fe(NO3)3·nH2O solution) was added at the beginning of preparation of TiO2 nanosheets while the surface modified sample was prepared from the aqueous suspension of undoped TiO2 nanosheets annealed at 800 °C and solution of 57Fe(NO3)3·nH2O via impregnation method. The volume modified sample was later annealed at 650, 800, and 950 °C, no further annealing was done on the surface modified sample. Both types of prepared materials were characterized by electron microscopy, X-ray powder diffraction, surface and porosity measurements, thermal analysis, FTIR and Raman spectroscopies, and Mössbauer spectroscopy. Photocatalytic activity was characterized from the results of 4-chlorophenol (4-CP) decomposition.
