Mesoporous materials and catalysis
The research about mesoporous materials is divided into two main projects: synthesis of mesopourous silica particles and films and the effect of synthesis parameters, and doping of mesoporous structures to be used in catalysis.

Catalytic reactions in mesoporous materials
In the field of nanomaterials many properties change with the size of the crystallites, and one of those properties is the catalytic activity. Not only does the surface area increase with reduced crystallite size, but the number of active sites on the crystal surface also increases. In order to have a large available surface area, mesoporous silica is used as a matrix for the catalysts, e.g. the silica walls can be doped with metals and nanoparticles are grown in the mesopores.
The catalytic activity or the synthesized materials is studied in a 100 ml high pressure reactor connected to a GC-MS, and a range of analytic techniques are further used to study the surface of the catalysts, e.g. FTIR and chemisorption.
The figure shows the reactor used for studies of catalytic reactions.
