Porous carbon monoliths have been synthesized using furfuryl alcohol as a carbon precursor in the nanocasting technique.The highest surface area of 1225 m~2g"‘was found for the carbon monolith exhibited the micropore volume of 0.85 cm~3 g~(-1).The various functional groups have been obtained on the surface of the adsorbent which increases its basicity as confirmed from the XPS analysis.The dynamic CO2 uptake was 1.0 mmol g~(-1) at 30°C using temperature swing adsorption set up under 12.5% CO2 flow.The effect of various adsorption temperatures along with CO2 concentrations on the adsorption capacity was also investigated.The increase in the CO2 uptake capacity by rising the temperature from 30°C onwards to 100°C confirms the involvement of exothermic and physisorption process.Also,the experiments for five adsorption-desorption cyclic runs were conducted for the regeneration study,indicating the good stability and reusabilty of the samples.
