Silica-montmorillonite nanoarchitectures

Similar silica-montmorillonite nanoarchitectures have also been prepared by sol-gel, as reported by Qian et al., using TEOS and another type of clay (from Zhangjiakou, China), corroborating the usefulness of this methodology in the development of silica-silicate-based porous materials [58]. 

As reported by Fuentes-Alventosa et al. [60], more complex silica-clay nanoarchitectures can also be prepared by sol-gel chemistry coupled with intercalation procedures combining montmorillonite and silica from TEOS, but in this case in the presence of a polysaccharide (pullulan). The resulting bionanocomposite is of...
