Synthesis of Zeolites in Reverse microemulsions, HighAspect RatioCrystals, and Novel Materials.
Abstract
The present invention provides methods for synthesizing porous silicon materials based on microemulsions that allows for an early preorganization of the silicon. This can lead to a crystalline material that is porous and has a powder XRD pattern that does not match any known zeolite material. The invention also provides a method for using microemulsions to synthesize (at the nanoscale) crystals with aspect ratios up to 100. Aspect ratio of crystals are important for magnetic properties, optical materials to generate polarized light, and physical properties of composites. The invented methods open up a whole new area by making it possible to synthesize a much broader range of materials in microemulsions to control the morphology.
Application(s)
New porous silicon materials with controlled structure, and nanoporous materials having porosity on the order of molecular dimensions and above are highly desirable for a wide range of applications including:
� Absorbents
� Gas and liquid separations
� Catalysts
� Ion-exchange materials
� Biomimetic materials
