Amine-functionalized adsorbents show broad application prospects in the field of flue gas CO₂ capture. However, the development of support materials with excellent CO₂ capture performance and facile synthesis method is still a challenge. In this work, mesoporous carbon (MC) with the ultra large pore volume of 3.1 cm³/g is synthesized by direct carbonization of the mixture of adipic acid and zinc powder without further chemical/physical activation process. The synthesized MC was then impregnated with tetraethylenepent amine (TEPA) to prepare the adsorbent. The formed ultra large pore volume and abundant mesopores structure could promote adsorption active site dispersion, thereby improving CO₂ adsorption performance. As a result, the MC support loaded with 80 wt% TEPA exhibits a large CO₂ capture amount of 5.3 mmol/g at 75 ℃ with 15 vol%CO₂. In addition, the carbon dioxide adsorption capacity is only 8.1 % less than that of the fresh adsorbent after 10 adsorption cycles, indicating that this adsorbent has excellent cycling stability. Noted that the synthesis of MC significantly improves the CO₂ adsorption performance while simplifying the support material preparation process. Thus, it is believed that the MC material is promising adsorbent support for highly efficient CO₂ capture.

胺基功能化吸附剂在烟气CO ₂捕集领域具有广阔的应用前景。然而，开发具有优异CO ₂捕获性能和简便合成方法的载体材料仍然是一个挑战。在这项工作中，通过将己二酸和锌粉的混合物直接碳化，无需进一步的化学/物理活化过程，合成了具有 3.1 cm ³ /g超大孔体积的介孔碳 (MC) 。然后将合成的 MC 用四亚乙基五胺 (TEPA) 浸渍以制备吸附剂。形成的超大孔体积和丰富的介孔结构可以促进吸附活性位点分散，从而提高CO ₂吸附性能。因此，负载为 80 wt% TEPA 的 MC 载体在 75 ℃、15 vol% CO _{2 下}表现出5.3 mmol/g的大 CO ₂捕获量。此外，经过10次吸附循环后，二氧化碳吸附量仅比新鲜吸附剂低8.1%，表明该吸附剂具有优异的循环稳定性。注意到MC的合成显着提高了CO ₂吸附性能，同时简化了载体材料的制备过程。因此，相信MC材料是用于高效CO ₂捕获的有希望的吸附剂支持。
