In this work, polyethyleneimine impregnated multi-walled carbon nanotubes (MWCNT) were successfully prepared by wet-impregnation method for changing surface properties. Specific surface area decreased as increase of PEI loading, but adsorption of CO2 exhibited different tendency. From the results of the TGA analysis optimized for CO2 adsorption, it was seen that adsorption capacity toward CO2 was enhanced after impregnation of PEI. Regeneration properties of CO2 adsorption/desorption were also investigated from TGA method. The results suggested that as prepared PEI impregnated MWCNTs have superior cycle characteristics. |
