摘要： The surfaces of porous sorbent materials are chemically modified to specifically target the adsorption of select gas phase constituents. More specifically, a functionalized cobalt (II) phthalocyanine-modified porous substrate capable of nitric oxide adsorption from a gas stream is provided. A soluble cobalt (II) phthalocyanine compound can be incorporated in a porous substrate by grafting soluble cobalt (II) phthalocyanine molecules onto a functionalized substrate. In an exemplary case, a cigarette filter element comprises the substrate, which can be an imidazole-functionalized silica gel or an activated carbon of high surface area and permeability, and the gas stream is the mainstream smoke of a cigarette.
