Abstract
A method of pore-size selective chemical modification of materials having pores of about 1 to 1,500 nm is disclosed. The resulting novel porous materials are particularly useful as separation media in chromatography, for selective isolation, adsorption and catalysis.
Claims14
A selectively modified material comprising a porous material having pores of at least two different size ranges, with the pores of one size range having surface groups of one functionality and the pores of another size range having surface groups of a different functionality wherein the pores are substantially homogeneously distributed throughout the material.
