本文报道了具有高表面密度氨基官能团的碳质材料的合成及其对CO（2）的吸附和封存。通过元素分析、N（2）吸附、扫描和透射电子显微镜、zeta电位、TGA和FTIR测量对富含氨基的碳质材料进行了表征。详细讨论了这些材料在CO（2）捕集中的应用。该材料显示出对CO（2）的显著吸附能力（在-20 ° C和1巴下为4.3 mmol g（-1））。此外，它们在低温和高温下都表现出对CO（2）比对N（2）高的表观选择性。
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.
