Ti-MCM-48 mesoporous materials have been synthesized by sequential addition
of alkoxides. The atomic ratio of Si and Ti in the synthesis gel was 40 an
d 5, respectively. The materials were characterized by means of powder XRD,
Nz adsorption-desorption measurements, HREM, Si-29 MAS NMR, diffuse reflec
tance FT-IR spectroscopy, electrophoretic mobility measurements and electro
n probe microanalysis.
