A novel synthesis route was developed for the cubic member of the M41S family, MCM-48, with a three-dimensional
pore system allowing the formation of submicrometre- to micrometre-sized beads with a narrow pore-size distribution.
The synthesis is based on the modified Sto¨ber method applying tetraethoxysilane, ethanol, water, ammonia and nhexadecyltrimethylammonium
bromide as template. The specific surface area, the specific pore volume and the average
pore diameter were varied in the following ranges: 900–1600 m2 g−1, 0.5–0.9 cm3 g−1 and 2–3 nm. Aluminium-,
chromium-, gallium-, niobium- and vanadium-MCM-48 were also synthesized following this procedure. © 1999
