Nanostructured materials for catalysis, separation and sensing

Periodic mesoporous materials (PMMs) are prepared using surfactants and polymers as supramolecular templates. They exhibit high surface area, and exquisitely ordered pore structure with adjustable sizes from 2 to ca. 10 nm in diameter. Since the discovery of the first periodic mesoporous silicas in early nineties, our group made significant contributions to the development of this field. One of our most important achievements was the discovery of an innovative method to expand in a controlled manner the pore size and volume of mesoporous silica from typically 3.5 nm and 0.8 cm3/g up to unprecedented 25 nm and 3.6 cm3/g without loss of surface area (> 1000 m2/g). One of the major thrusts of the proposed research is the rational design of mesoporous (more generally nanostructured) materials, their preparation, characterization and applications in such areas as catalysis, separation and chemical sensing.
