Carbon dioxide capture on amine-rich carbonaceous materials derived from glucose.
The synthesis of carbonaceous materials with a high surface density of amino functions for CO(2) sorption and sequestration is reported. The amino-rich carbonaceous materials are characterized by elemental analysis, N(2) sorption, scanning and transmission electron microscopy, zeta potential, TGA and FTIR measurements. A detailed discussion on the use of these materials in CO(2) capture is provided. The materials show significant sorption capabilities for CO(2) (4.3 mmol g(-1)at -20 degrees C and 1 bar). Furthermore, they show a high apparent selectivity for CO(2) over N(2) at both low and high temperatures.
