Abstract
A method of immobilizing a metal catalyst in a porous support includes additively forming a precursor structure on a substrate from a metal catalyst and at least one of a metal oxide or a metal cluster compound; exposing the precursor structure to a vapor of an organic linker; and reacting the at least one of the metal oxide or the metal cluster compound in the precursor structure with the organic linker to form a porous support that immobilizes the metal catalyst.
