Controlling the orderliness and pore size of mesoporous silica COK-12
Laura M. Henning, Technische Universität Berlin, DE
Ordered mesoporous silica COK-12, such as the well-known SBA-15, is characterized by high surface areas and defined mesopores, making it interesting for a variety of applications, such as catalysis, adsorption, or drug delivery. However, in contrast to common hydrothermal synthesis pathways, COK-12 can be synthesized at atmospheric pressure and near neutral pH, utilizing inexpensive sodium silicate as a precursor. This presentation deals with the effect of an additional aging step at different temperatures during the synthesis. Its effect on the orderliness and pore size of COK-12 could be ascertained with SAXS.
These lectures are free and can be attended via Zoom by to up to 100 attendees.
The lectures will be recorded as well, and (with permission of the presenter) will be made available online afterwards for a broader educational reach.
