“…These properties can be tailored to enhance adsorption performance towards a specific adsorbate; i.e., hydrophobic activated carbons are oxidised to increase their hydrophilic character for liquid phase adsorption applications, or for their implementation in PSA driers [20]. It is well established that the electron-deficient carbon atom of CO 2 can act as a Lewis acid and participate in stabilizing reactions with Lewis base groups such as amines [21]. As a result, research has focussed on the incorporation of nitrogen functionalities onto the surface of activated carbons to promote their performance as adsorbents in CO 2 capture applications [22][23][24][25][26].…”

The effect of oxidation upon the CO 2 capture performance has been studied taking a phenolic resin carbon as the base material. Oxygen surface groups were introduced through liquid and gas phase oxidation treatments, using ammonium persulfate, nitric acid and air, respectively.The surface chemistry of the final carbon is strongly affected by the type of oxidation treatment: liquid phase oxidation introduces a greater amount of oxygen, mostly as carboxylic groups; these are absent in the gas phase oxidised sample that contains mainly ether and carbonyl functionalities. The porous texture of the samples is also affected by the oxidation treatment: through liquid phase oxidation the pore volume is somewhat reduced, while this is slightly developed by air treatment at 693 K. Despite the reduction in the porous volume and the acidic surface, liquid-phase oxidised samples present greater CO 2 adsorption capacity than the starting carbon due to Lewis acid-base interactions with the CO 2 molecule.Moreover: oxidised samples are easily regenerated, and observed heats of adsorption are † Corresponding Author: Tel : +34 985 119090; E-mail address: frubiera@incar.csic.es.

Oxidation is therefore proposed as a plausible modification technique for developing easy-to-regenerate carbon adsorbents with enhanced CO 2 capture performance.
