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.
