Abstrakt:	Highlights: [•] Commercially available and more cost effective support has been used for the synthesis of the new adsorbents. [•] Amine compounds are chemically bonded to the support preventing amine leaching and minimizing their environmental and health hazard. [•] More cost effective regeneration step due to significantly lower heat capacity (≈0.73Jg−1 °C−1) compared with aqueous solutions. [•] First example of one step grafting of trimethoxysilylpropyl-polyethyleneimine onto silica for the synthesis of CO2 adsorbent materials. [•] Enhanced graft densities were obtained by the saturation of the silane agents with CO2 before grafting to the surface. [ABSTRACT FROM AUTHOR]
