at lower pressure. The adsorption isotherms show that the nanocomposite has a good CO 2 adsorption affinity compared to MIL-101. The best adsorption capacity is about 1.6 mmol g −1 obtained for the nanocomposite material which is two times higher than that of MIL-101, indicating strong interactions between CO 2 and MIL-101@g-C 3 N 4 . This difference in efficacy is mainly due to the presence of the amine groups dispersed in the nanocomposite. Finally, we have developed a simple route for the preparation of an effective and new adsorbent for the removal of CO 2 , which can be used as an excellent candidate for gas storage, catalysis, and adsorption.

“…The synthesised PPY/PB nanocomposite exhibits superior thermal stability compared to that of similar materials reported in the literature. 30,31 Structural characterization of the PPY/PB nanocomposite Powder X-ray diffraction was used to identify the crystalline phases and sizes in PPY, PB and in the nanocomposite. The PXRD pattern of PPY shows an amorphous nature with a broad hump at a 2y value of 25.81 (Fig.…”

The mesoporous silica SBA-15 functionalized with various amines was prepared and then doped with copper (Cu ++). The modified materials were tested for the retention of CO 2 at room temperature using temperature-programmed desorption (CO 2-TPD). Several parameters affecting the CO 2 retention capacity (CRC) were investigated such as effect of the nature of amine groups, repetitive adsorption-desorption cycles and dispersion of copper. CO 2-TPD and H 2 O-TPD were employed in order to correlate the hydrophilic character with the CO 2 retention capacity. The obtained results showed that amines-functionalized mesoporous materials containing their own moisture have good results towards the retention of CO 2. Especially the triamine-functionalized SBA-15 has the greatest CRC value which results in the increase of the number of adsorption sites. The reuse of these solids in three adsorption/desorption cycles showed higher stability with a slight decrease in CRC. The dispersion of copper showed a progressive decrease in the CRC value. The correlation between the Cu% and the CRC shows that the value of the CRC decreases with increasing Cu% due to complexation of the adsorption sites (amines) by acid sites (copper).
