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 CO2 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 CO2 capture is provided. The materials show significant sorption capabilities for CO2 (4.3 mmolg(-1) at -20 degrees C and 1 bar). Furthermore they show a hig apparent selectivity for CO2 over N-2 at both low and high temperatures.
