Activated‐carbon nanofibers (ACNFs) provide a relatively new, modified structure of carbon‐based adsorbents that have the ability to adsorb carbon dioxide due to their high specific surface area, wide distribution of porous structures, and high volume of active sites. In this study, cost‐effective agricultural waste‐based graphene synthesized from rice husk ashes was used as additive to enhance the ACNF properties. ACNF/graphene (gACNF) is still a relatively unexplored adsorbent. The resultant gACNF exhibited better thermal stability properties, with higher yield, larger specific surface area, and higher micropore volume. These properties are the main factors contributing to their enhanced adsorption performance towards CO₂.

活性炭纳米纤维/石墨烯纳米复合材料及其对二氧化碳的吸附性能

活性炭纳米纤维（ACNFs）提供了一种相对较新的，改性的碳基吸附剂结构，由于其比表面积高，多孔结构的分布范围广以及活性位点数量大，因此具有吸附二氧化碳的能力。在这项研究中，由稻壳灰合成的具有成本效益的基于农业废物的石墨烯被用作增强ACNF性能的添加剂。ACNF /石墨烯（gACNF）仍是一种尚未开发的吸附剂。所得的gACNF表现出更好的热稳定性质，具有更高的产率，更大的比表面积和更高的微孔体积。这些性质是有助于其增强对CO ₂吸附性能的主要因素。
