Amine-modified solid sorbents are potentially good candidates for postcombustion CO 2 capture. We synthesized a series of amine-modified mesoporous silica sorbents, and measured their CO 2 adsorption capacities. Among them, mesoporous silica MSU-H modified with (3-trimethoxysilylpropyl)diethylenetriamine, denoted by TA/MSU-H(II), showed high CO 2 adsorption capacity of 3.08 mmol/g-sorbent at 60 °C with 15 kPa of CO 2 , 12 kPa of H 2 O vapor and 74 kPa of N 2 as similar as the postcombustion CO 2 capture condition. Furthermore, we confirmed that the CO 2 adsorption capacity of TA/MSU-H(II) after 30 cycles of the adsorption at 60 °C and the desorption at 120 °C was 2.98 mmol/g-sorbent. © 2013 The Author.
