La. Bondar et al., SYNTHESIS AND SOME PROPERTIES OF TITANIUM-CONTAINING SILICA-GELS, Reaction kinetics and catalysis letters, 50(1-2), 1993, pp. 193-198
Microporous silica gels containing small amounts of titanium ions have
been synthesized. Porous structure and surface active sites of silica
gels have been studied. It has been found that the titanium ions are
distributed uniformly in silica gel matrix, substituting silicon ions
isomorphically.
