Nanoparticle-doped Mesoporous Silicates / Synthetic Developments and Applications in Catalysis

Abstract
This proposal seeks to build upon DWB's discovery of a general route to nanoparticle-doped, nanostructured silicates that uses simple and off-the-shelf reagents in a true liquid crystal templating methodology. The proposal is in two, linked parts. In the first, the general methodology will be extended to: encompass a wider range of metals; exert control over particle size and metal oxidation state; employ block co-polymer templates to access cubic pore morphologies and to extend the preparation of bimetallic particles. The second part focuses on real-world catalytic applications using catalysts produced using this methodology, namely automotive exhaust emission control and selective hydrogenation of allylic species.

Description | We have shown that control of pore size in templated porous silicas can influence rates of catalysis beneficially as a mix of pore sizes addresses issues concerned with mass transport. |
Exploitation Route | We have also shown high rates of catalysis in nanoparticle-doped porous silicas of the SBA-15 family where the silica is produced via true liquid crystal templating, which method also gives control over the mesa-pore/micro-pore balance. |
