Synthesis of Highly Ordered, Extremely Hydrothermal stable SBA-15/Al-SBA-15 under the Assistance of Sodium Chloride

In this paper, highly ordered, extremely hydrothermal stable SBA-15/Al-SBA-15 has been synthesized using mixed surfactants (triblock copolymer, P123, and semifluorinated surfactant, FSO-100) as a template at a high aging temperature (140−180 °C) with the assistance of NaCl. Thus - synthesized SBA-15 maintained the well-resolved SXRD patterns and high surface area, large pore size, and high pore volume after being hydrothermally treated at 100 °C for 300 h or 600 °C for 6 h, whereas less-ordered SBA-15 was synthesized at such high temperatures without the addition of NaCl. Furthermore, highly hydrothermal stable Al-SBA-15 has been synthesized with tetrahedral Al totally incorporated in the framework.
