High‐Temperature Generalized Synthesis of Stable Ordered Mesoporous Silica‐Based Materials by Using Fluorocarbon–Hydrocarbon Surfactant Mixtures

Abstract

Highly ordered mesoporous silica materials are hydrothermally synthesized at high temperature by using fluorocarbon–hydrocarbon surfactant mixtures as templates. Because of the high temperature of the synthesis, the obtained materials show complete silica condensation, which give rise to ultra-stabile structures. JLU-20 for example (see TEM image of calcined JLU-20) has a fully condensed mesopore wall with a very high Q4/Q3 ratio of 6.5.
