Phase transition of silica in the TMB-P123-H2O-TEOS quadru-component system: A feasible route to different mesostructured materials

- Various silicas are obtained in the TMB-P123-H2O-TEOS quadru-component system.
- MLVs are developed from HEX structure and eventually evolve into MCF structure.
- The phase transition process of various silicas is explained by packing parameter.
