Abstract

A new and efficient method for the preparation of MCM-41 type mesoporous silicas using phosphate as promoter under reflux conditions is reported. All silica (Si-MCM-41), alumino-silicate (Al-MCM-41) and titanium-silicate (Ti-MCM-41) mesoporous materials were studied. Instead of following conventionally used autoclave method at autogeneous pressure, the synthesis was carried out by reflux method under atmospheric pressure. Addition of small quantity of phosphate ions (PO43-), used as promoters, significantly reduced the synthesis time of all these mesoporous materials. The quite high surface areas (930-1480 m2 g-1) of all these MCM-41 samples were typical of MCM-41 type ordered mesoporous materials.
