1. An anion exchange membrane, comprising:
a porous support membrane comprising an outer surface, wherein the porous support membrane is in the form of a non-woven fabric or mesh, veil, knit fabric, woven fabric or mesh, open-cell structure, fibril and node structure, or open-cell foam; and
a layer comprising a silica-based ceramic that forms a coating on at least a portion of the outer surface of the porous support membrane, wherein the silica-based ceramic comprises quaternary ammonium groups covalently bound to the silica-based ceramic, and wherein the silica-based ceramic has an average pore diameter of less than or equal to 10 nm.
