Amine-functionalized nanomaterials have significant potential in CO2 capture technology because of their low energy consumption
stable performance
and high regeneration capacity. To improve the CO2 adsorption capacity
the high surface and mesoporous SBA-15 was used as the support for amine modification and CO2 adsorption. The adsorbents prepared with different modified methods
amines and amine content were characterized by using the BET
XRD
FT-IR
thermo-gravimetric analysis
and TG adsorption test technologies. The adsorption results showed that the grafting of mixed amine modified APTES-SBA (U)-T60 with a high adsorption capacity of 192.05 mg/g under pure CO2 at 75℃
which is higher than that of solvent extraction and calcination method. Mixed amine modified adsorbents exhibited a high thermal stability and reproducibility.
