Silica modified with amino groups possesses adsorption properties of carbon dioxide. We have synthesized amine-modified silica by the combination of co-condensation and surface modification method, which exhibited adsorption of 400ppm of low-concentration carbon dioxide with high utilization efficiency of amino groups. In this research, we investigated the effect of synthesis condition of amine-modified silica on the property for adsorption of low-concentration carbon dioxide.
