摘要
The use of fossil fuels for energy production is accompanied by carbon dioxide release into the environment causing catastrophic climate changes. Meanwhile, replacing fossil fuels with carbon-free nuclear energy has the potential to release radioactive iodine during nuclear waste processing and in case of a nuclear accident. Therefore, developing efficient adsorbents for carbon dioxide and iodine capture is of great importance. Two nitrogen-rich porous polymers (NRPPs) derived from 4-bis-(2,4-diamino-1,3,5-triazine)-benzene building block were prepared and tested for use in CO2 and I-2 capture. Copolymerization of 1,4-bis-(2,4-diamino-1,3,5-triazine)-benzene with terephthalaldehyde and 1,3,5-tris(4formylphenyl)benzene in dimethyl sulfoxide at 180 degrees C afforded highly porous NRPP-1 (SA(BET) = 1579 m(2) g(-1)) and NRPP-2 (SA(BET) = 1028 m(2) g(-1)), respectively. The combination of high nitrogen content, pi-electron conjugated structure, and microporosity makes NRPPs very effective in CO2 uptake and 12 capture. NRPPs exhibit high CO2 uptakes (NRPP-1, 6.1 mmol g(-1) and NRPP-2, 7.06 mmol g(-1)) at 273 K and 1.0 bar. The 7.06 mmol g(-1) CO2 uptake by NRPP-2 is the second highest value reported to date for porous organic polymers. According to vapor iodine uptake studies, the polymers display high capacity and rapid reversible uptake release for 12 (NRPP-1, 192 wt % and NRPP-2, 222 wt %). Our studies show that the green nature (metal-free) of NRPPs and their effective capture of CO2 and 12 make this class of porous materials promising for environmental remediation.
