Abstract

We investigated the synthetic parameters of MCM-41, prepared through the evaporation-to-dryness treatment of alkali-free surfactant-silicate mixture, and their thermal stability and water resistance. The product obtained by this method gave a well-ordered 2D-hexagonal structure after the removal of surfactant molecules by either solvent-extraction or calcination. It is noteworthy that the d 100 value of MCM-41 remained almost the same after calcination, indicating that the pore wallsof the as-made product were dense and rigid. This MCM-41 shows a high degree of thermal stability and water resistance due to the highly dense silicate framework in the mesopore walls.
