Abstract: The greenhouse effect which is mainly caused by carbon dioxide has become a global concern. CO₂ capture and storage (CCS) is an effective technology that enables the capture of CO₂ from fuel combustion or industrial processes and its storage underground, thereby preventing it from entering the atmosphere. Recent research process on the capture of CO₂ from high temperature flue gas by lithium silicate ceramic material is summarized, including the theory of CO₂ capture, the preparation of lithium silicate ceramic materials, the factors affecting CO₂ capture capacity, as well as the technological process of CO₂ capture from high temperature flue gas. Furthermore, challenges and future work for the development of this field are proposed.

Key words: carbon dioxide; lithium silicate ceramics; high temperature separation; coal combustion
