Abstract

Abstract Non-thermal plasma has revealed as fast and efficient strategy for the complete elimination of template molecules from SBA-15 materials. Through comparing the textural properties of a set of SBA-15 materials obtained by classical calcination and non-thermal plasma treatment new insights to the SBA-15 structure could be revealed. As such, a third type of microporosity could be disclosed by the use of non-thermal plasma for SBA-15 synthesized at 60 °C. Additionally, starting from a synthesis temperature of 100 °C, template elimination through non-thermal plasma allows for preserving native textural properties of as-synthesized SBA-15. The developed alternative treatment combines the advantages of improved textural properties and higher silanol density, hence making the strategy very promising for superior applications of SBA-15 materials.
