Patent ID: 7632773

Claim:
A method for manufacturing a supported nanocatalyst, comprising, (i) exposing a porous support material to a gaseous solvent at a concentration that exceeds atmospheric concentration and for a time period greater than 2 hours in order for the gaseous solvent to be absorbed into the pores of the support material without causing substantial cracking of the porous support material; (ii) preparing a nanocatalyst solution by mixing a liquid solvent, a plurality of catalyst atoms, and a plurality of control agent molecules, reacting the plurality of catalyst atoms with the plurality of control agent molecules to form complexed catalyst atoms, and allowing or causing the complexed catalyst atoms to form a plurality of nanoparticles; and (iii) impregnating the porous support material with the nanocatalyst solution while at least a portion of the gaseous solvent is still present in the pores of the support material, thereby yielding a supported catalyst.
