Synthesis and functionality
of innovative porous clay hybrid nanostructures
Metallic nanoparticles or their oxides play an important role in catalysis, optical or biomedical applications.
Therefore it is desirable to explore new supports, which will increase the degree of nanoparticles dispersion and
availability. The promising group of materials used as the supports are the ones derived from nano-modified clay minerals.
This project is devoted to the design and development of functionalized porous materials based on low-cost and eco-friendly
clay minerals from smectite group for catalytic applications, e.g. removal of volatile organic compounds from the atmosphere.
The stability and functionality of the new generation supported catalysts with selected heteroatoms will be performed.
Our investigation will focus on direct functionalization of purely siliceous mesoporous silica and porous clay heterostructure
composites derived from layered clay minerals by site selected incorporation of iron into the structure. The impact of such
functionalization, the resulting properties of functionalized composites e.g.: the close neighbourhood of iron, possible transformations,
the coordination and oxidation states will be investigated with the use of Mossbauer spectroscopy in comparison with infrared FTIR spectroscopy.
