Spherical carbon was synthesised from chitosan, which was impregnated with different compositions of barium by ‘wet impregnation method’ and subsequently activated by thermal treatment. The as-prepared carbon and barium-activated carbons were characterised for their textural, thermal properties and elemental composition using SEM, EDS, CHN analyser, TGA, FT-IR, XRD and BET surface area analyser. The surface area of the unimpregnated carbon was found to be around 20 m 2 /g, whereas that of carbon impregnated with 10, 20 and 30 wt% barium was found to be 259.01, 106.60, and 99.21 m 2 /g, respectively. The TGA results showed that the barium-loaded carbons have higher thermal stability (beyond 500 ° C) as compared to the unloaded carbon. Moreover, the 10 wt% barium-loaded carbon exhibited a CO 2  adsorption capacity of 86.23 mg/g at ambient temperature with excellent regeneration, which was higher in comparison with the unimpregnated carbon that possessed 60.00 mg/g. Being CO 2  a weak Lewis acid molecule, the barium-activated carbon, which is a weak base, could positively influence its CO 2  adsorption capacity.
