Determine whether the hexagonal mesoporous molecular sieve MCM-41 can form under ambient room-temperature conditions without hydrothermal treatment.
Prepared aqueous reaction mixtures containing silicate precursors and alkyltrimethylammonium surfactant templates at room temperature.
Characterized the resulting precipitates over time to assess the structural formation and long-range hexagonal ordering of the silica framework.
Demonstrated the spontaneous formation of well-ordered MCM-41 molecular sieves at room temperature.
Established that elevated hydrothermal temperatures are not an absolute requirement for surfactant-mediated mesophase silicate ordering.
