ABSTRACT

The clay fraction of saponite-rich samples from western Macedonia, Greece was used
for the preparation of TiO2 –pillared saponite. Nanocomposites of titania saponite were
prepared by solvothermal reaction using water and ethanol as the solvent,
hexamethylene tetramine as the precipitant and titanium trichloride as the precursor.
Phase composition, particle morphology, element content and physical properties were
characterized using X-Ray Diffraction (XRD), Scanning Electron microscopy with
Microanalysis (SEM-EDS), Attenuated Total Reflection using Fourier Transform
Infrared Spectroscopy (ATR-FTIR), Inductively Coupled Plasma Mass Spectrometry
(ICP-MS), particle size analysis using Dynamic Light Scattering method (DLS), and
porosimetry analysis. The results show that TiO2 –pillared saponite was successfully
synthesized and that the product exhibits improved properties for more demanding uses
and applications.
