Abstract: Global warming has become a big problem to human’s survival and development. Thus，researches on CO₂ absorption materials have attracted more and more attention.In this paper，several technologies are described for the capture and concentration of carbon dioxide，such as solvent absorption and adsorption. The adsorption technologies can be divided into several categories according to its matrix，including metal oxide，fiber materials，activated carbon materials，molecular sieve materials，carbon nanotubes and polymer materials. The research progress of each technology is discussed，and their advantages and disadvantages are introduced briefly. It indicated that amino modified carbon nanotubes are promising materials for the absorption of carbon dioxide.

Key words: absorption materials, carbon dioxide（CO₂）, adsorption, capture, carbon nanotube
