Nanoporous Silicon and Gallium Nitride Materials
The design of new porous materials is crucial for the development of new solid catalysts. Solid base catalysts like silicon nitride revceive considerable interest in recent years since they are propsective materials for the production of fine chemicals. We have designed silcon nitride materials with extremely high specific surface area (1000 m2g-1) and pore volume (0.48 cm3g-1). With the use of templates microporous silicon nitride materials are obtained with a narrow pore size distribution and well defined pore size. Such materials have high thermal stability and are also ideal candidates for high temperature applications under non-oxidizing conditions.
