摘要

在CO

直接空气捕集（DAC）技术中，寻求廉价且湿度稳定性较好的变湿吸附材料，对于提高变湿吸附剂的实用性和环境适应性十分重要。以活性炭（AC）为基材，通过负载碳酸钾制备了多孔复合变湿吸附剂K

/AC，对比研究了木质、煤质和椰壳活性炭基复合变湿吸附剂的物理性质和CO

吸附性能，并进一步对价廉的木质活性炭基复合变湿吸附剂进行了亲疏水改性，研究了环境湿度对其性能的影响。结果表明，椰壳活性炭基复合变湿吸附剂具有最优的湿度稳定性，在常温、相对湿度为30%时，其CO

吸附容量达到最大值（0.85 mmol/g），这主要得益于其更优的孔隙结构和相对较高的疏水性。亲水改性的木质活性炭基复合变湿吸附剂在湿度增大时吸附容量迅速减小；而疏水改性的吸附剂则具有更好的湿度稳定性，在相对湿度为30%时，其CO

吸附容量最大（0.81 mmol/g）。通过疏水改性提高变湿吸附剂的CO

吸附性能及环境适应性，有利于促进DAC技术的广泛应用。

Abstract

In the CO

direct air capture (DAC) technology

finding low-cost and humidity-stable moisture-swing adsorption materials is crucial for enhancing the practicality and environmental adaptability of the adsorbents. The porous composite humidity adsorbent K

/AC was prepared by loading potassium carbonate on activated carbon (AC). The physical properties and CO

adsorption performance of the adsorbents based on wood

coal

and coconut shell activated carbon were studied and compared. Furthermore

hydrophilic and hydrophobic modifications on the low-cost wood activated carbon based adsorbent were conducted and the impact of ambient humidity on adsorbent performance was investigated. The results show that the coconut shell activated carbon based composite moisture adsorbent has the best humidity stability

and its CO

adsorption capacity reaches the maximum value (0.85 mmol/g) at room temperature and relative humidity of 30%. This is primarily attributed to its superior pore structure and relatively high hydrophobicity. Besides

the hydrophilic modified wood activated carbon-based adsorbent exhibits a rapid decline in adsorption performance as humidity increases

whereas the hydrophobic modified adsorbent demonstrates better humidity stability

with optimal CO

adsorptio

n performance reaching 0.81 mmol/g at room temperature and relative humidity of 30%. Enhancing the CO

adsorption performance and environmental adaptability of moisture-swing adsorbents through hydrophobic modification holds great potential for promoting the wider application of DAC technology.
