Project A04
Controlled Synthesis of Mesoporous Silica Materials
Mesoporous silica materials set the present benchmark for mesoporous materials in terms of thermal and chemical stability. By means of liquid crystal templating this project aims to push the limits of current silica materials and extend their application to the field of molecular heterogeneous catalysis. This includes (i) an extension of the currently available pore diameters to a range of 8 – 20 nm, necessary for the attachment of bulky molecular catalytic systems, (ii) the precise control of the mean pore diameter to enable conclusive studies of confinement effects and (iii) the exploration of new pore geometries such as elliptical or chirally structured pores.
