A TiO&#x2014;SiOaerogel and TiO&#x2014;SiOaerogel monolith with a regular and predeterminable shape and an ordered mesoporosity and a method of making the aerogel and aerogel monolith, using surfactants in preparing the SiOsol before mixing with TiOsol. The aerogel obtained by this method has a specific surface area greater than 400 m/g and a pore volume larger than 0.5 cc/g.

Titania-silica aerogel monolith with ordered mesoporosity and preparation thereof

A rapid and inexpensive technique for generating nanotextured surfaces is disclosed. The technique involves the (1) creation of regular, nanometer-sized template by microwave assisted hydro- or solvo-thermal treatment of polymer films coated on surfaces followed by (2) coating of a layer of metal, metal oxides, polymers and inorganic materials. The nanometer-sized polymer template could be removed to create regularly shaped, hollow nanostructures (e.g., nano-bottles, nano-bowls, nano-holes etc.).

Methods for preparing nanotextured surfaces and applications thereof

The present invention features a catalytic material which includes a metal catalyst anchored to a nano-sized crystal containing a metal oxide. Furthermore, the present invention features a method of producing the catalytic material described herein. Finally, the present invention features using the catalytic material for removing contaminants and for getting the desired products.

Catalytic material and method of production thereof

The present invention relates to a titanium dioxide material for coating on a substrate and method of making the same. The coated material is resistant to delamination and can be used for air-purification purposes.
