Article abstract The urgent need for sustainable and innovative approaches to mitigate the increasing levels of atmospheric CO2 necessitates the development of efficient methods for its removal. In this study, we focus on the new, innovative approach for synthesis and functionalization of metal-organic framework (MOF) ZIF-8 in one step at room temperature to enhance its capacity for CO2 capture. Specifically, we investigated the impact of four amino-compounds, namely tetraethylenepentamine (TEPA), hexadecylamine (HDA), ethanolamine (ELA), and cyclopropylamine (CPA), on the chemical structure, size, surface area and porosity, and CO2 capturing of ZIF-8 powder. By varying concentrations of the amino-compounds, we examined their influence on the ZIF-8 properties. Our findings demonstrate that each amino-compound and its respective concentration exhibit distinct effects on the characteristics of ZIF-8. Notably, the ZIF-8 sample functionalized with the highest presented concentration of TEPA exhibited significant improvement in CO2 trapping efficiency, with a 33.3% enhancement. Moreover, least concentrated samples with added HDA or CPA demonstrated notable improvements with enhancements of 46.6% and 18.6%, respectively. These results highlight the potential of simple synthesis and functionalization techniques for MOFs in enhancing their CO2 capture capabilities. The findings from this study offer new opportunities for the development of strategies to mitigate CO2 emissions using MOFs.学术论文《氨基改性ZIF-8用于强化CO₂捕集：合成、表征与性能评价》的配套数据集。 数据集版本： V1：本数据集为该论文所使用实验数据的首个版本。 V2：本数据集为全新整理版本，包含已发表论文所使用的全部实验数据，更多详细信息可参阅README文件。 论文摘要 面对大气CO₂浓度持续攀升的现状，开发高效的CO₂脱除方法已成为可持续与创新性减排技术的迫切需求。本研究聚焦于一种创新性的室温一步合成策略，对金属有机骨架（metal-organic framework, MOF）ZIF-8进行功能化改性，以提升其CO₂捕集能力。具体而言，本研究选取四乙烯五胺（tetraethylenepentamine, TEPA）、十六烷基胺（hexadecylamine, HDA）、乙醇胺（ethanolamine, ELA）以及环丙胺（cyclopropylamine, CPA）四种氨基化合物，探究其对ZIF-8粉体的化学结构、粒径、比表面积、孔隙结构以及CO₂捕集性能的影响。通过改变氨基化合物的添加浓度，本研究系统考察了其对ZIF-8各项性能的调控作用。研究结果表明，不同氨基化合物及其添加浓度对ZIF-8的各项性能均具有差异化影响。值得注意的是，采用最高浓度TEPA改性得到的ZIF-8样品，其CO₂捕集效率提升最为显著，增幅达33.3%。此外，添加低浓度HDA与CPA的ZIF-8样品同样表现出优异的性能提升，增幅分别为46.6%与18.6%。上述结果证实了通过简便的合成与功能化改性策略提升MOFs材料CO₂捕集性能的可行性。本研究成果为开发基于MOFs材料的CO₂减排策略提供了全新的研究思路。
