Abstract:
The properties of borosilicate fiberglass supports were studied using a set of physicochemical techniques (BET; transmission electron microscopy; IR spectroscopy; and 11B, 23Na, 27Al, and 29Si NMR spectroscopy). Unleached fiberglass was characterized by the presence of silicon primarily in the Q2 form (two silicon atoms in the second coordination sphere of silicon–oxygen tetrahedrons) and by a comparatively homogeneous distribution of concomitant heteroatoms (B, Al, and Na). Under the action of an acid, the extraction of nonsilica components and the rearrangement of a silicon–oxygen framework (the transition of Q2 to Q3+ Q4) took place simultaneously. This was accompanied by the development of the surface and by the formation of channels with a wide range of sizes: from channels 15–50 Å in diameter (the adsorption properties of these channels are similar to those of mesopores in ordinary silica supports) to microchannels, which are typical of pseudolayer intercalation structures described previously for leached soda–silica fiberglass.
