Use of Ionic Liquid as Template for Hydrothermal Synthesis of the MCM-41 Mesoporous Material

resumo

In this study the MCM-41 mesoporous material was first prepared by using hydrothermal method in the presence of 1-butyl-2,3-dimethylimidazolium hexafluorophosphate ([BMMIM]PF6) ionic liquid (IL) as template. The IL presented the average yields between 67 and 76%. The obtained MCM-41 showed the main structural parameters associated with the formation of condensed silica (Si - O - Si), a hexagonal mesostructure with a compact arrangement of cylindrical tubes and agglomerated spherical particles.
