In recent years,the climate changes caused by greenhouse gas have been a global concern.CO_2 emission has been considered the most important factor for the climate change.The research and development of the lithium-based solid sorbent for adsorbing CO_2 at high-temperature is reviewed.The preparation method for lithium-based sorbent,CO_2 sorption-desorption behavior,modification methods and development of low-cost lithium-based sorbent are reviewed and discussed in detail.Combining with the current CO_2 capture situation,the current challenges faced in the development of lithium-based adsorbing materials are proposed and its future research focus is also prospected.
