Abstract
Mesoporous silica with hexagonal structure was synthesized by liquid-crystal templating method at room temperature. The synthesized products showed a narrow pore size distribution at around 2.0 nm in pore redius and the high specific surface areas at around 1100 m2/g. The crystallization kinetics of the mesoporous silica has been studied using differential thermal analysis (DTA). The activation energies of crystal growth obtained from the modified Kissinger-equation are 332 kJ/mol for the mesoporous silica with and 242 kJ/mol for the nonporous silica without surfactant template. The crystallization kinetics of Ti- and V-containing mesostructured silica was also discussed.
