In this work, the multi-walled carbon nanotubes (MWCNTs)-porous silicas have been synthesized by hydrolysis with tetraethylorthosilicate (TEOS). Also, the prepared samples were impregnated with polyethyleneimine (PEI) for increasing of CO2 adsorption properties. The CO2 adsorption capacity was evaluated by TGA method in 15% CO2 condition, which was similar condition with fossil-fuel power plants. Pristine MWCNTs showed a low CO2 adsorption capacity due to their low microporosity. However, the MWCNT-porous/PEI had higher CO2 adsorption capacity and good cycle stability in CO2 capture experiment with TGA method. |
