Abstract:CO2 capture technologies using solid adsorbents are promising approach to reduce environmental pollution resulting from CO2 emission. In this study, silica xerogel derived from cheap precursor was used as a CO2 adsorbent after polyethyleneimine (PEI) functionalization. Fourier transform infrared (FTIR) analyses indicated that PEI functionalized silica xerogels were successfully prepared. N2 adsorption-desorption isotherms revealed that PEI loading decreased specific surface area and pore volume of the neat sil… Show more
