Mesoporous-silica films, fibers, and powders by evaporation

Patent Bruinsma, Paul J. ; Baskaran, Suresh ; Bontha, Jagannadha R. ; Liu, Jun

This invention pertains to surfactant-templated nanometer-scale porosity of a silica precursor solution and forming a mesoporous material by first forming the silica precursor solution into a preform having a high surface area to volume ratio, then rapid drying or evaporating a solvent from the silica precursor solution. The mesoporous material may be in any geometric form, but is preferably in the form of a film, fiber, powder or combinations thereof. The rapid drying or evaporation of solvent from the solution is accomplished by layer thinning, for example spin casting, liquid drawing, and liquid spraying respectively. Production of a film ismore »« less

Mesoporous silica film from a solution containing a surfactant and methods of making same

Patent Liu, Jun ; Domansky, Karel ; Li, Xiaohong ; Fryxell, Glen E ; Baskaran, Suresh ; Kohler, Nathan J ; Thevuthasan, Suntharampillai ; Coyle, Christopher A ; Birnbaum, Jerome C

The present invention is a mesoporous silica film having a low dielectric constant and method of making having the steps of combining a surfactant in a silica precursor solution, spin-coating a film from this solution mixture, forming a partially hydroxylated mesoporous film, and dehydroxylating the hydroxylated film to obtain the mesoporous film. It is advantageous that the small polyoxyethylene ether surfactants used in spin-coated films as described in the present invention will result in fine pores smaller on average than about 20 nm. The resulting mesoporous film has a dielectric constant less than 3, which is stable in moist airmore »« less

Sample Desorption/Onization From Mesoporous Silica

Patent Iyer, Srinivas ; Dattelbaum, Andrew M.

Mesoporous silica is shown to be a sample holder for laser desorption/ionization of mass spectrometry. Supported mesoporous silica was prepared by coating an ethanolic silicate solution having a removable surfactant onto a substrate to produce a self-assembled, ordered, nanocomposite silica thin film. The surfactant was chosen to provide a desired pore size between about 1 nanometer diameter and 50 nanometers diameter. Removal of the surfactant resulted in a mesoporous silica thin film on the substrate. Samples having a molecular weight below 1000, such as C.sub.60 and tryptophan, were adsorbed onto and into the mesoporous silica thin film sample holder andmore »« less

Synthesis of attrition-resistant heterogeneous catalysts using templated mesoporous silica

Patent Pham, Hien N. ; Datye, Abhaya K.

The present invention relates to catalysts in mesoporous structures. In a preferred embodiment, the invention comprises a method for encapsulating a dispersed insoluble compound in a mesoporous structure comprising combining a soluble oxide precursor, a solvent, and a surfactant to form a mixture; dispersing an insoluble compound in the mixture; spray-drying the mixture to produce dry powder; and calcining the powder to yield a porous structure comprising the dispersed insoluble compound.
