Publikováno v: Microporous and Mesoporous Materials. 143:174-179
This paper presents an easy way to obtain a material with CO2 sorption properties by using commercially available MCM-41. In order to increase MCM-41 CO2 sorption capacity, 2.48 mmol g−1 of amine groups were anchored onto silica surface. A few care
