Greenhouse gas predominantly emission from the burning of fossil fuels lead to a series of environmental problems, the capture and storage of greenhouse gas have become the key to addressing this issue. Herein, we present the facile synthesis of a series of porous carbon materials derived from porous aromatic frameworks constructed from commercially available and cheap building units via chemical activation. In contrast with the precursor porous aromatic frameworks, the porosity of such activated porous carbon materials is greatly boosted and the resulting porous carbon materials feature excellent surface areas up to 2863 m² g⁻¹ and total pore volumes as high as 1.348 cm³ g⁻¹. The abundant microporous properties endow the materials with considerable greenhouse gases of CO₂ and CH₄ adsorption ability at ambient conditions, exhibiting that at 273 K and 1 bar the CO₂ capture capacity is as high as 6.09 mmol g⁻¹, comparable to those reported porous carbon materials synthesized for this key adsorption. Ideal adsorption solution theory predicts that the prepared porous aromatic frameworks and their derived porous carbon materials display decent CO₂/N₂ and CH₄/N₂ selectivities, and thus their construction and properties may pave a new avenue for greenhouse gas capture and separation.

温室气体主要来自化石燃料的燃烧排放，导致一系列环境问题，温室气体的捕集和封存成为解决这一问题的关键。在此，我们介绍了一系列多孔碳材料的合成，这些材料源自多孔芳香骨架，这些骨架由市售且廉价的建筑单元通过化学活化构建而成。与前体多孔芳香骨架相比，这种活性炭多孔碳材料的孔隙率大大提高，所得多孔碳材料具有高达2863 m ²  g ^{-1 的}优异表面积和高达1.348 cm ³  g ^{- 的}总孔体积^{。 1}. 丰富的微孔特性使材料在环境条件下具有相当大的温室气体 CO ₂和 CH ₄吸附能力，表明在 273 K 和 1 bar 下，CO ₂捕获能力高达 6.09 mmol g ^-1，与报道的相当为这种关键吸附而合成的多孔碳材料。理想吸附溶液理论预测，制备的多孔芳香骨架及其衍生的多孔碳材料显示出良好的CO ₂ /N ₂和CH ₄ /N ₂选择性，因此它们的结构和性质可能为温室气体捕获和分离铺平道路。
