Thermogravimetric investigations during the synthesis of silica-based MCM-41
(Kluwer Academic Publ, 2001-01-01)
MCM-41 material was synthesized starting from hydrogel containing colloidal fumed silica, sodium silicate, cetyltetramethylammonium bromide (CTMABr) as surfactant, and distilled water as solvent. These reactants were mixed ...
