A highly porous spherical carbon material produced from resorcinol-formaldehyde resin and sugars was applied as an efficient CO sorbent. The effect of the modification with different sugars on the physicochemical properties of the obtained materials was investigated. As a result, very efficient CO adsorbents have been obtained. Produced materials expressed high CO uptake values, reaching 6.79 mmol/g at 0 C and 1 atm for the sample modified with xylitol. In addition, the selectivity of the sugar modified samples towards CO has been significantly improved in comparison to the reference resorcinol-formaldehyde resin derived sample. The incorporation of sugars resulted in changes in the crystallographic structure of the samples leading to obtaining more disordered carbon materials.

间苯二酚-甲醛树脂和糖类球形碳的 CO2 吸附研究

由间苯二酚-甲醛树脂和糖生产的高度多孔球形碳材料被用作高效的二氧化碳吸附剂。研究了不同糖的修饰对所得材料的理化性质的影响。结果，获得了非常有效的CO吸附剂。生产的材料表现出高 CO 吸收值，用木糖醇改性的样品在 0℃和 1 atm 下达到 6.79 mmol/g。此外，与参考间苯二酚-甲醛树脂衍生样品相比，糖改性样品对 CO 的选择性得到了显着提高。糖的掺入导致样品晶体结构的变化，从而获得更无序的碳材料。
