Název v původním jazyce

Infrared and Raman spectroscopy of three commercial vermiculites doped with cerium dioxide nanoparticles

Popis výsledku v původním jazyce

Three commercial vermiculites and these vermiculites doped with cerium dioxide nanoparticles were investigated by infrared and Raman spectroscopy. Infrared spectroscopy in middle infrared region (4000 - 400 cm-1) was supplemented by separation of overlapped spectral bands in the region of stretching vibration of hydroxyl groups. Detailed structural properties of vermiculites were completed based on the Raman spectroscopy in the spectral region between 800 and 100 cm-1 and X-ray diffraction analysis. Raman spectroscopy provided evidence of trioctahedral-dioctahedral vermiculite-mica in original vermiculite and trioctahedral phyllosilicate structures in vermiculites after precipitation procedure of cerium dioxide nanoparticles. The wavenumber shifts of the Raman bands at about 670 cm-1 and 190 cm-1 in spectra of vermiculites showed strong trend with increasing Fe3+ and Al substitution in tetrahedra and octahedra, respectively.
