Abstract
Composites of Mg-Al LDH and ASG were prepared by various methods, and their acidic and basic gas adsorption properties were investigated by CO2 and NH3 gas TPD. Of the various preparation methods, composite samples prepared by precipitation of LDH in an ASG sol solution showed a superior adsorption for both acidic and basic gases. The adsorption was higher than the arithmetic mean of the LDH, which mainly adsorbs acidic gas and the ASG, which mainly adsorbs basic gas. These composites could be good candidates as adsorbents and deodorants for the simultaneous uptake of acidic and basic adsorbates, i.e. materials with dual function adsorption properties.
