Microporous titanosilicates and other novel mixed octahedral-tetrahedral framework oxides

Stable microporous materials, such as zeolites, are extremely important for applications in catalysis, adsorption, ion-exchange, and separation. In th is review we describe a new class of stable microporous materials that invo lves novel mixed octhaedral-tetrahedral framework oxides. The archetypal ma terial is based on titanosilicates, although there is tremendous scope for introducing many other transition metals. These materials not only have pot ential novel applications in the fields normally associated with zeolites b ut also possible applications in the areas of optoelectronics, nonlinear op tics, batteries, magnetic materials and sensors.
