Amorphous silica-based organoamine-functionalized hybrid materials were designed through polymer-derived ceramics (PDCs) route, in order to selectively transport CO₂. Silicon-based perhydropolysilazane (PHPS) polymer was chemically modified with an alkylamino silane derivative, and subsequently oxidized in air at room temperature to afford organoamine-functionalized silica. The effect of the organoamine functionalization in the powdered sample as well as for the membrane is discussed with regard to the pure PHPS-derived amorphous silica.
