“…48,76 However, according to analytical studies and calculations, such processes could not change the total number of bonds of titanium oxychloride groups with the silicon support surface (i.e., the total number of Si7O7Ti bonds). Hence, it can be assumed that the increase in the absorption band intensity observed for the Si7O7Ti bond in the IR spectra was associated with an increase in the degree of connectivity of an individual TiCl x group due to its interaction with the silanol groups that did not react earlier with TiCl 4 .…”
