Layered double hydroxide (LDH) has attracted great attention due to the ability of incorporating negatively charged (bio-)organic molecules and inorganic clusters into the interlayer spaces. In this study, we have directly incorporated aminoacid molecules into layered double hydroxides such as Zn-Al LDH, Mg-Al LDH, and Ca-Al LDH via traditional co-precipitation method. Since the amine group of intercalated aminoacid can capture CO2 by forming carbamic acid, aminoacids with different number of amino-group such as valine, phenylalanine, lysine, and argenine, were incorporated into the layered double hydroxides in order to compare the CO2 removal activity depending on the number of amine group in aminoacid. The interlayer structures of aminoacid intercalated LDH are characterized with X-ray diffraction analysis. The activity of removing CO2 was evaluated with volumetric CO2 gas adsorption-desorption isotherm analysis at different temperatures. The CO2-removal property of aminoacid intercalated LDH nanohybrids will be discussed in terms of the number of amine group in the aminoacid and the kind of layered double hydroxides.
