A series of carbonyl modified hyper-cross-linked polymers (HCPs) with different porosity was prepared and they were carbonized for production of oxygen-rich porous carbons. The results show that these carbons have high Brunauer-Emmett-Teller (BET) surface area (440–1769 m²/g) and outstanding microporosity (72–87%), the oxygen is greatly improved after the carbonization with the oxygen content of 20.7–29.2 wt%. The CO₂ uptake of PDVC-700-1 is the highest with the value of 303 mg/g at 273 K and 1.0 bar and PDV-pc has the highest CO₂/N₂ selectivity of 46.8. Interestingly, the CO₂ adsorption is linear correlated to the ultramicropore volume (d < 1.0 nm) with the correlation coefficient of 0.9935 (273 K, 1.0 bar) and the O content also plays a role in CO₂ adsorption. These porous carbons have medium adsorption heat (28.5–34.9 kJ/mol) with an excellent desorption and repeated use performance.

制备了一系列具有不同孔隙率的羰基改性超交联聚合物（HCP），并将其碳化以生产富氧多孔碳。结果表明，这些碳具有较高的Brunauer-Emmett-Teller（BET）表面积（440-1769 m ² / g）和出色的微孔率（72-87％），碳化后的氧随着氧含量的增加而大大改善。 20.7-29.2 wt％。PDVC-700-1的CO ₂吸收量最高，在273 K和1.0 bar下的吸收值为303 mg / g，PDV-pc的最高CO ₂ / N ₂选择性为46.8。有趣的是，CO ₂吸附与超微孔体积（d <1.0 nm）呈线性相关，相关系数为0.9935（273 K，1.0 bar），O含量也对CO ₂吸附起作用。这些多孔碳具有中等吸附热（28.5–34.9 kJ / mol），具有出色的解吸和重复使用性能。
