Thermochemical Capture of Carbon Dioxide on Lithium Aluminates (LiAlO2 and Li5AlO4): A New Option for the CO2 Absorption

“…There are only a few papers in which Li 5 AlO 4 has been synthesized and tested for some electrical applications. [19][20][21] Li 5 AlO 4 ceramic presents two different crystal polymorphs R-Li 5 AlO 4 and β-Li 5 AlO 4 , where both polymorphs have orthorhombic crystal structures. 22,23 If lithium aluminates were able to absorb CO 2 , then following reactions may occur The reactions proposed above are presented assuming that CO 2 is absorbed through the same mechanism observed for other lithium ceramics [24][25][26] in which lithium aluminates react to produce lithium carbonate in addition to a residual oxide, Al 2 O 3 .…”

“…LiAlO 2 has been proposed as a breeder ceramic into the fusion reactors, a solid electrolyte for lithium batteries, and ceramic carrier material in the fabrication process of electrolyte tiles for molten carbonate fuel cells, among other applications. − However, there is almost no information about Li 5 AlO 4 . There are only a few papers in which Li 5 AlO 4 has been synthesized and tested for some electrical applications. − Li 5 AlO 4 ceramic presents two different crystal polymorphs α-Li 5 AlO 4 and β-Li 5 AlO 4 , where both polymorphs have orthorhombic crystal structures. , …”
