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.

Carbon (CCUS) has four major methods, namely, pre-combustion, post-combustion, oxyfuel combustion, direct air capture. It been reported that applying CCUS up 95% produced running power plants. However, a cost penalty efficiency decrease hinder wide applicability CCUS. Advancements CCSU were made increasing decreasing sorbents.

Therefore, economic feasibility carbon footprint greatly limited by purification steps before electrolysis ($70–100 per ton for /N separation). In recent years, have exhibited importance this matter integrating capture electroreduction single unit. Mostly, solutions electrolytes been under attention, promising results achieved significantly improve overall economy RR. focus capture‐electroreduction integration can go beyond solution/electrolyte‐based (e.g., amine ionic liquids) other processes solid adsorption membrane‐based processes, more efficient options, be potentially integrated gas‐diffusion electrode design.
