In general, organosilicon chemistry and silica/silicate chemistry have been treated in different fields. However, these two chemistries are quite close, and in fact aqueous and nonaqueous sol-gel chemistry strongly links the two chemistries. The approach for the integration can be various, and in this seminar I would like to present chemistry of silica-, silicate-, and siloxane-based building blocks. These blocks are useful for the design of nanomaterials and nanocomposites. For example, two dimensional silicate minerals are exfoliated to form nanosheets which can be useful for the formation of nanocomposites formation. Nanosized silica- and siloxane-based components, such as mesoporous silica nanoparticles (MSN) and dendritic siloxane oligomers, should have high potentiality for applications because the surfaces can be modified in various ways.

Discovery and developments of mesoporous silica

Jeudi 19 Septembre 2013 de 09h30 à 11h,
ENSCM Amphithéâtre de Forcrand

The discovery of the formation of mesoporous silica derived from a layered polysilicate kanemite and some recent developments of mesoporous silica will be reviewed. The results on the formation of mesostructured silica-organic systems indicate that layered silicates are unique starting materials for the formation of mesoporous silica. Mesoporous materials can not be categorized as a sub-member of zeolites and they are related to much more diverse fields. The compositions, structures, and morphologies are controlled in various ways and this aspect is quite promising for future technological advancement in many fields, including catalysis, adsorption, host-guest chemistry, biomedicine, etc.
