The rising CO2 concentration in the atmosphere contributes significantly to global warming, necessitating effective carbon capture techniques. Amine-based solvents are widely employed for chemisorption of CO2, although they have drawbacks, such as degradation, corrosion, and high regeneration energy requirements. Physical adsorption utilizing microporous adsorbents is a viable alternative that offers excellent efficiency selectivity capture. This work presents facile one-pot synthesis 3D-triptycene-containing hyper-cross-linked polymer (TBPP-OH) possessing hydroxyl groups. presence triptycene units TBPP-OH polymeric structure gives several desirable features, inherent microporosity, larger surface area, improved thermal stability. showed considerable microporosity (%Vmic = 70%), BET-specific area (SABET) 838 m2 g–1, good stability (Td 372 °C char yield > 60%) which makes it promising adsorbent A strong affinity was shown by with Qst 32.9 kJ/mol demonstrating superior capacity 2.77 mmol/g at 273 K 1 bar pressure where volume micropore plays significant role. values over N2 CH4 were also estimated be reasonably indicating potential separation different applications. mechanism investigated using Langmuir dual-site models.
