1Role of Amine Functionality for CO2 Chemisorption on Silica.

Hahn MW1, Jelic J1, Berger E1, Reuter K1, Jentys A1, Lercher JA1.

J Phys Chem B. 2016 Mar 3;120(8):1988-95. doi: 10.1021/acs.jpcb.5b10012. Epub 2016 Jan 12.

The mechanism of CO2 adsorption on primary, secondary, and bibasic aminosilanes synthetically functionalized in porous SiO2 was qualitatively and quantitatively investigated by a combination of IR spectroscopy, thermogravimetry, and quantum mechanical modeling. The mode of CO2 adsorption depends particularly on the nature of the amine group and the spacing between the aminosilanes. Primary amines bonded CO2 preferentially through the formation of intermolecular ammonium carbamates, whereas CO2 was predominantly stabilized as carbamic acid, when interacting with secondary amines.
