摘　　要：首先介绍了CO_2捕集的背景;然后讨论了锆酸锂和硅酸锂等锂基高温CO_2吸收剂捕集CO_2的机理;重点介绍了近几年来锂基高温CO_2吸收剂的一些制备方法,并对不同方法制备的纳米锂基高温CO_2吸收剂的性能进行了比较;最后,从合成方向、CO_2吸收性能与吸收剂电导率的关联及在高温原位捕集CO_2中的应用3个方面,对锂基高温CO_2吸收剂的研究前景进行了展望.It was introduced the background of the CO2 capture followed by the discussion of CO2 absorption mechanism in the lithium-based high-temperature CO2 absorbents. Afterwards, various preparation methods of Li2ZrO3 and Li4SiO4 absorbents reported in recent years were highlighted. A comparison on the performance of nanocrystalline lithium-based CO2 absorbents prepared by different methods was made. Finally, the research prospect of the lithium based CO2 absorbents was outlooked from three aspects such as the trend of the synthesis, the relation build-up of the absorption and electric conductivity, as well as the applications in the insitu removal of CO2 at high temperatures.
