The search for better carbon dioxide capture material is attracting great attention because of the anthropogenic carbon dioxide emissions.  Porous materials are considered to be one of the most promising candidates. In this study, a series of porous, nitrogen-doped carbons derived from Task-Specific Ionic Liquids (TSILs) were synthesized and investigated as CO2 adsorbents. An exceptional CO2 uptake of as high as 168 mg of CO2 per g was achieved at room temperature (25�C) for the TSIL carbonized at 500 �C, showing a significantly higher capacity as compared to most porous carbon materials. The relationship among CO2 uptake and apparent surface area and the nitrogen content is described. The application of TSILs as precursors for porous materials provides a new avenue for the development of improved materials for carbon capture.Acknowledgment:  Research sponsored by the Office of Basic Energy Sciences, U.S. Department of Energy.
