“pH-jump” synthesis of 2D-rectangular c2mm mesoporous silica materials with helical morphology and extensive void defects

- MMT-1 materials with c2mm mesostructure were synthesized by a “pH-jump” method.
- Acetate esters were used as pH modifiers.
- The materials had helical channels and extensive void defects.
- The mesostructure, particle shape and the extent of void defects could be modulated.
- The materials exhibited excellent hydrothermal stability.
