Polyfurfuryl alcohol (PFA) and poly n-methyl aniline (PNMA)-derived precursors are synthesized. The resulting polymer precursors are pyrolized under argon with and without KOH. The induced porosities and textural properties are determined via methyl chloride porosimetry method. Gas adsorption properties of the carbons are evaluated by measuring adsorption of CO2 on the carbons at room temperature and elevated pressures. The PFA-derived carbons are essentially microporous with pore modes between 0.5 and 1 nm. Such a small pore size of the carbons enhances the CO2 adsorption uptake . The effect of KOH activation and CO2 oxidation on the poresize and also presence of nitrogen heteroatom in the carbon framework of PNMA-derived carbon on the CO2 uptake is studied . KOH activation method compared to CO2 oxidation is showing higher adsorption capacities. This behavior cannot only be explained by the effect of poresize and presence of alkali metals inside the pores is expected to significantly contribute to the gas adsorption uptake.
