Abstract
The xerogels, containing phosphonic acid groups ≡Si(CH2)2P(O)(OC2H5)2 in the surface layer of their particles, are synthesized by the sol-gel method (ethanol as a solvent and fluoride ion as a catalyst). It is shown that, when 2 : 1, 3 : 1, and 4 : 1 tetraethoxysilane/(diethylphosphatoethyl)triethoxysilane ratios are used, nonporous substances are formed, whereas, at 6 : 1, 8 : 1, and 10 : 1 ratios, the xerogels with highly porous structures are produced (the specific surface area is 505–534 m2/g, the sorption pore volume is 0.34–0.53 cm3/g, and the pore diameter is 3.6–4.6 nm).
