Recent advances in lithium containing ceramic based sorbents for high-temperature CO2 capture

Recently, lithium containing ceramic based high-temperature CO 2 sorbents have received tremendous attention due to their high CO 2 capture capacity, low regeneration temperatures, and relatively high stability. With the rapid development of these promising CO 2 capturing materials, a timely review is highly demanded. In this contribution, we critically summarize the performance of all types of lithium containing ceramics including lithium silicates, zirconates, titanates, aluminates, ferrites, cuprates, bismuthates and borates for capturing CO 2 at high temperatures. For these CO 2 sorbents, all possible schemes for improving their CO 2 capture capacity, kinetics, and cycling stability have been comprehensively reviewed. Their potential applications in high-temperature post-combustion CO 2 capture from stationary flue gases, sorption enhanced methane steaming reforming, sorption enhanced alcohol reforming, and CO oxidation coupled with subsequent CO 2 capture processes are compared and discussed. We hope this work can inspire and guide researchers from a wide range of backgrounds and help pave the way for major breakthroughs in both fundamental studies and industrial applications in this field
