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

Lead Research Organisation: University of York
Department Name: Chemistry

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.
