Abstract:Carbon dioxide (CO2) adsorption on a nanoporous carbon (CMK-1) and a polyaniline modified nanoporous carbon (CMK-1/PANI) are investigated and compared in this study. The structural order and textural properties ofthe synthesized materials have been studied by XRD, FT-IR and nitrogen adsorption-desorption analysis. The isotherms of these unmodified and modified samples have been investigated using volumetric method at 298 K and the pressure ranging from 1 to 5 bar.It was found that CMK-1/PANI exhibits significant adsorption for CO2 adsorption.The adsorption mechanism which is based on electrostatic attraction is described.
