Abstract

Different Al-containing Li₄SiO₄ samples (Li _4+x(Si_1-xAl_x)O₄ solid solutions) were obtained by mechanosynthesis and then characterized structurally (X-ray diffraction (XRD) and solid-state NMR) and microstructurally (N₂ adsorption and scanning electron microscopy (SEM)). While solid-state NMR results showed that the aluminum (silicon) presented some distortion after the milling process, the milling process tended to increase the Li _4+x(Si_1-xAl_x)O₄ surface areas. The samples were tested dynamically and isothermally in the CO₂ chemisorption at high temperatures. In the second case, a complete kinetic analysis was produced. It was evidenced that aluminum addition and the new microstructural features produced during the milling process importantly increase the CO₂ capture, in comparison to the Li₄SiO ₄ phase and the Li_4+x(Si_1-xAl _x)O₄ solid solutions prepared by solid-state reaction.
