Development of efficient amine-modified mesoporous silica SBA-15 for CO2 capture

- A secondary amine AN-TEPA is used to modify the SBA-15.
- CO2 adsorption capacity (180.1 mg g−1-adsorbent for 70% amine loading) is high.
- The sorbent exhibits a high stability after 12 cycling runs.
- The modified SBA-15 achieves complete desorption at low temperature (100 °C).
