Abstract A novel CO 2 sorbent was prepared by impregnating mesoporous silica, SBA-15, with acrylonitrile (AN)-modified tetraethylenepentamine (TEPA) in order to increase CO 2 adsorption capacity and improve cycling stability. The mesoporous silica with pre-and post- surface modification was investigated by X-ray diffraction characterization (XRD), N 2 adsorption–desorption test (N 2-BET), transmission electron microscopy (TEM), Fourier ...
