Реферат:
The physicochemical properties and structure of supports prepared by leaching soda–silica fiberglass materials were studied using a set of physicochemical techniques (BET; IR spectroscopy; transmission electron microscopy; and 29Si, 23Na, 27Al, 133Cs, and 129Xe (of adsorbed molecules) NMR spectroscopy). A matrix that corresponded in chemical composition to SiO2 was formed at high degrees of leaching; however, it was considerably different from ordinary silica gels in properties. The structure and properties of this matrix are most adequately described by the model of a pseudolayer intercalation structure, which includes alternating layers of several silicon–oxygen tetrahedrons separated by narrow (<4 Å) cavities. Considerable amounts of OH groups (∼5000 μmol/g) are contained in these cavities, and these OH groups are different from the surface hydroxyl groups of ordinary globular silica. Although the interlayer spaces are small, comparatively bulky cations can be intercalated into them.
