Abstract

Li₄SiO₄ to be used as a CO₂ absorbent are synthesized by used SiO₂ and Li₂CO₃. The crystal structure of the Li₄SiO₄ materials were analyzed using a X-ray powder diffractometer (XRD), the microstructure of all the samples were observed using the method of scanning electron microscopy (SEM) and the CO₂-absorption ability of the Li₄SiO₄ materials were studied using a thermo gravimetric analyzer (TG). The results showed that after 5 years in the air, the CO²-absorption ability of Li₄SiO₄ was decreased because of water absorbed by Li₄SiO_4.
