Abstract

The N-doped carbon aerogel materials were investigated to explore their potential use in carbon dioxide (CO2) capture. Carbon aerogels were prepared from a nitrogen-containing polymer precursor using urea as nitrogen source into the polymer matrix through the sol-gel method. CO2 capture performances were evaluated from 273 to 298K at 1 bar. CO2adsorption is influenced by the micropores and amount of a nitrogen-containing the samples. N2 adsorption isotherms have showed different structures of these carbon materials. CO2 adsorption capacities up to 3.6 mmol/g (298K) and 4.5 mmol/g (273K) were achieved. Both texture and surface chemistry affect the CO2 capture performance of the adsorbents.
