Abstract

Different Al-containing Li4SiO4 samples (Li 4+x(Si1-xAlx)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(Si1-xAlx)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 Li4+x(Si1-xAl x)O4 solid solutions prepared by solid-state reaction. © 2013 American Chemical Society.
