HIGHLY DISPERSED TITANIUM(IV) OXIDE ON ALPHA-CELLULOSE SURFACE - AN XPS, SEM, AND XRD STUDY

Interaction of titanium chloride with a cellulose surface and the decurrent modifications introduced on its morphology were studied by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The chemical analysis of the surface was carried by X-ray photoelectron spectroscopy (XPS) and changes in the crystallinity upon chemical treatment was determined by the X-ray diffraction (XRD) technique. Interaction of titanium with cellulose occurs only at the surface and a decrease of its crystallinity was observed with the amount of metal oxide incorporated into the solid matrix.
