Among the various classes of mesoporous materials, MCM-48 has an interpenetrating network of three-dimensional pores and hence is thought to possess favorable mass transfer kinetics compared to the unidimensional pores that occur in MCM-41. The synthesis of MCM-48 is dependent on a number of factors such as temperature, stirring rate, reactant ratios, type and chain length of surfactant employed, nature of solvent and Si precursor. The shortest time reported so far for the preparation of MCM-48 and metal substituted MCM-48 is 5 h. It is attractive to pursue methods to shorten the time frame of synthesis further. In addition, it is better if the reported synthetic methods are carried out at ambient conditions and is fairly easy and reproducible. Here we present a method for the facile synthesis of siliceous MCM-48 in as little time as 30 min.
