Funkcionalizace mezoporézních silikátových materiálů
Modification of surface of silicates materials with organic functional groups has been widely investigated in recent years. The modified materials are used in separation technology, electronic devices, controlled drug delivery and in chemical processes using immobilized catalysts. Two main methods of preparation of the materials are reviewed. The one-pot synthesis of support and its reaction with a modification agent leads to the product with even distribution of active groups but less ordered structure. The other methods are based on post-grafting of the modified support surface. The disadvantage of the latter method is often uneven distribution of active groups.
