“…Traditional resins with the nonpolar St-DVB framework often have low gas adsorption even if they have a high BET surface area . In order to improve the CO 2 adsorption capacity of porous materials, including the adsorption resin, the most popular methods are the impregnation of organic amines, − porous liquid ions, , a hybrid nitrogen element, , and the introduction of F-containing or O-containing groups. − As for the separation of C 2 H 4 /C 2 H 6 on resin, ion-exchange resin was generally modified by Ag(I) as a kind of C 2 H 4 -selective adsorbent because a π-complex can be formed between Ag(I) and C 2 H 4 . Although these strategies have been verified to be very effective, some shortcomings still cannot be ignored.…”
