1. A method for coating a substrate, the method comprising:

  • (a) adding at least one compound of Formula [Z1Z2SiCH2]3 (Ia) into an aqueous mixture that contains essentially no structure directing agent or porogen to form a solution, wherein each Z1 represents a hydroxyl group, a C1-C4 alkoxy group or an oxygen atom bonded to a silicon atom of another compound and each Z2 represents, a hydroxyl group, a C1-C4 alkoxy group, a C1-C4 alkyl group or an oxygen atom bonded to a silicon atom of another compound;

    (b) adding an adsorbent material to the solution to form a slurry;

    (c) coating the slurry onto a substrate;

    (d) aging the slurry; and

    (e) drying the slurry to obtain a coating comprising the adsorbent material and a binder comprising an organosilica material which is a polymer comprising independent units of Formula [Z3Z4SiCH2]3 (I), wherein each Z3 represents a hydroxyl group, a C1-C4 alkoxy group or an oxygen atom bonded to a silicon atom of another unit or an active site on the substrate and each Z4 represents a hydroxyl group, a C1-C4 alkoxy group, a C1-C4 alkyl group, an oxygen atom bonded to a silicon atom of another unit or an active site on the substrate.
