Shaping silica to mesoscale architectures at room-temperature

DOI

Hierarchical zeolites with molecular order at both the micropore (<2nm) and mesopore (2-50nm) level are able to combine confinement effects in catalysis without suffering from diffusional limitations. Unfortunately, the key question standing central towards hierarchical zeolite synthesis - "should one “meso-shape” condensed silica before bulk crystallisation, or create this organisation with already crystalline structures?" has not at all been answered. We have in earlier work shown that several popular structures, such as stacked zeolite sheets and MCM-41 can obtain their meso-scale order already during the process of silica condensation at room temperature. The proposed work intends to build on these results, and reveal the dynamics of structure-directing agents in structure direction at the meso-level. The work will contribute to the development of industrially relevant materials.
