A sorbent article having a substrate having porous channel walls defining open channels, and an organic-inorganic hybrid sorbent material distributed on a surface of the porous channel walls, wherein the sorbent material is derived from an amino-functionalized alkoxysilane and a polyamine, wherein the sorbent material is present in an amount equal to or greater than 10 g/l, wherein at least some of the sorbent material resides in the porous channel walls and forms CO2 adsorption sites within the interior of the porous channel walls. The article may be useful, for example, for removing CO2 from a gas. |
