Summary on Grant Application Form
Mesoporous molecular sieves (MMS), particularly mesoporous silica, have great potential as catalyst supports. The attraction of MMS is that they offer the opportunity to order the immobilised catalysts much more rigorously than is possible on traditional amorphous or nanocystalline supports. Furthermore, the pores are so much larger than those in traditional molecular sieves such as zeolites that even bulky substrates can freely access catalytic sites. At the same time, the large pore size enables much bulkier molecules, eg. heteropolyacids, to be immobilised in MMS than in zeolites. Supercritical fluids (SCFs) are becoming increasingly important in materials processing and as an environmentally acceptable solvent for chemical reactions. This project aims to combine the properties of MMS and SCFs to make new materials with catalytic properties and to carry out new chemistry with them. A key feature of our collaboration is that material scientists, Materials scientists, chemists and chemical engineers are working in the same laboratory space, recently refurbished under the JIF scheme. We propose (1) to apply SCFs for the preparation of new MMS hosts and immobilised catalysts, (2) to evaluate catalysts for a range of gas phase and SCFs reactions including hydrogenation, hydroformylation, Friedel-Crafts alkylation, etc. (3) to develop new immobilised catalysts for the photochemical reduction of C0,. The project will also involve collaboration with researchers at the University of York and the Free University of Armsterdam.
