Intensification of CO2 capture by active sites in functional ionic liquids
Carbon capture,utilization and storage(CCUS)technology has become an important part of China's carbon neutral technologies.Compared with the organic amine absorbers conventionally used in the industrial field,functional ionic liquids with low volatility,high stability and site designability show unique advantages in CO2 capture by chemical absorptions.The research progress of functional ionic liquids for CO2 capture in recent years was reviewed.The structural classification and synthesis strategies of functional ionic liquids were briefly described.Three types of active sites(nitrogen site,oxygen site and carbon site)of functional ionic liquids and the corresponding capture mechanisms were described in detail.And the future research directions of CO2 capture by functional ionic liquids were prospected.
