제목 Highly reproducible SO2 adsorbent with super capacity via functionalized Covalent Organic Framework
초록 Removing SO2 from the exhaust flue gases of fossil fuel power plants has been an important issue for its toxicity and environmental problems. Here in, we successfully developed new series of imide-linked COFs, which have high mesoporosity with large surface areas as the gas flowing channels, incorporating 4-[(dimethylamino)methyl]aniline (DMMA) as the modulator to imide-linked COF. We observed that the functionalized covalent organic frameworks as the SO2 adsorbent have exhibited the outstanding molar SO2 adsorption capacity, PI-COF-m10 recorded 6.30 mmol SO2 g-1 (40 wt%), and to our knowledge; it is the best reported record among organic SO2 adsorbents up to now.  Furthermore, the adsorbed SO2 was completely desorbed in short time with remarkable reversibility. These results suggest that channel-wall functional engineering could be a facile and powerful strategy to develop mesoporous COFs for high performanced and reproducible gas storage and separation.
