SUPPORTED CATALYSTS USING NANOPARTICLES AS THE SUPPORT MATERIAL

Document Type and Number:

WIPO Patent Application WO2005002714

Kind Code:

A3

Abstract:

A process for making a porous catalyst, comprises a) providing an aqueous solution containing a nanoparticle precursor, b) forming a composition containing nanoparticles, c) adding a first catalytic component or precursor thereof and a pore-forming agent to the composition containing nanoparticles and allowing the first catalytic component, the pore-forming agent, and the nanoparticles form an organic-inorganic structure, d) removing water from the organic-inorganic structure; and e) removing the pore-forming agent from the organic-inorganic structure so as to yield a porous catalyst.
