Abstract

High quality cubic SBA-16 can be synthesized rapidly at room temperature in 1 h using low surfactant concentrations and has 65% of micropore volume and 5.3 nm of wall thickness on average. The structure integrity of SBA-16 is very sensitive to the acid concentration in gel because of the necessity of moderate hydrogen-bonding and electrostatic interaction between silicates and surfactants.
