cze Analýza Fe center v zeolitech s využitím UV-VIS-NIR, IS spekter a voltametrie. Efekt přípravy, koncentrace Fe a typu zeolitu. V práci byla zaměřena na identifikaci individuálních Fe center v zeolitech, tj. k přítomnosti Fe iontů v kationtových pozicích, Fe-oxo komplexů a Fe-oxidů za využití kombinace UV-Vis-NIR spekter, IR spekter skeletálních vibrací a adsorpce NO, a voltametrie. zeolity, adsorpce molekul NO, IČ spektra
eng Analysis of Fe species in zeolites by UV-Vis-NIR, IR spectra and voltammetry. Effect of preparation, Fe loading and zeolite type A combination of UV-Vis-NIR spectra, IR spectra of skeletal vibrations and of adsorbed NO, and voltammetry were employed to distinguish individual Fe species in zeolites, i.e. the occurrence of the single Fe ions at cationic sites, dinuclear Fe-oxo complexes and Fe oxides. zeolites, adsorption of NO molecule, IR spectra
