Recently, extensive researches were performed on carbon dioxide (CO) capture using nano solvents. In this study, three different modified magnetic nanoparticles (NPs), including FeO-Proline (FeO-P), FeO-Lysine (FeO-L), and FeO@SiO-NH NPs were produced to alter and enhance the properties of FeO NPs for CO capture in sulfinol-M as a base solvent. CO capture experiments were carried out in a high-pressure batch apparatus in which CO absorbed into sulfinol/nano-sulfinol. The influences of NP type, NP loading, and gas phase pressure on CO capture were studied. Based on the obtained results, FeO-L and FeO@SiO-NH NPs are notably capable on increasing the CO capture capacity of sulfinol-M, and they improved CO capture up to 6.3% and 13.36% as compared with the base fluid. Moreover, experiments indicated that all nanosolutions have higher CO capture efficiency at higher pressures. Eventually, the effect of NPs stability on CO capture was investigated and discussed.
最近，人们对使用纳米溶剂捕获二氧化碳（CO）进行了广泛的研究。在这项研究中，制备了三种不同的改性磁性纳米颗粒（NPs），包括 FeO-脯氨酸（FeO-P）、FeO-赖氨酸（FeO-L）和 FeO@SiO-NH NPs，以改变和增强 FeO NPs 的性质，用于在磺基醇-M 中作为碱性溶剂捕获 CO。在高压间歇式装置中进行 CO 捕获实验，其中 CO 被吸收到磺基醇/纳米磺基醇中。研究了 NP 类型、NP 负载和气相压力对 CO 捕获的影响。根据实验结果，FeO-L 和 FeO@SiO-NH NPs 显著提高了磺基醇-M 的 CO 捕获能力，与基础流体相比，CO 捕获能力提高了 6.3%和 13.36%。此外，实验表明，所有纳米溶液在较高压力下具有更高的 CO 捕获效率。最后，研究并讨论了 NPs 稳定性对 CO 捕获的影响。
