CO2 and CH4 adsorption on periodic mesoporous organosilica: A DFT study

Autor: Paula Ferreira, Mirtha A.O. Lourenço, José R. B. Gomes

Periodic mesoporous organosilicas (PMO) were proposed as potential adsorbents for CO2/CH4 adsorption-separation due to their strong interactions with CO2 and low affinity for CH4. Herewith, we present a comprehensive density functional theory (DFT) s
