In the current work, synthesised Magnesium Tetraphenylporphyrin (MgTPP) functionalised with ethylenediamine (EDA) loaded onto Polyetherimide (PEI) nanofibers were fabricated by means of electrospinning. The ability of the developed membrane for potential CO₂ and PM_2.5 capture was evaluated. Ethylenediamine, the chelating agent was loaded onto the fibrous structure; the introduced amino group pendants captured CO₂ molecules effectively. Structural evidence was revealed by infrared spectroscopy. The average diameter of the amino modified MgTPP/PEI nanofibers was found to be in the range of 1.2–1.4 μm and possessed a high thermal stability of 411 °C. The contact angle measurements proved the hydrophilic nature of the filter. The fibrous membrane possessed high CO₂ and PM_2.5 filtration capacity of 74% and 81% respectively with extraordinary non-zero dust loading capacity. Finally, the significance of the addition of EDA for CO₂ adsorption was proved statistically.

乙二胺功能化的金属卟啉负载纳米纤维膜：空气过滤的新战略方法。

在当前的工作中，通过静电纺丝法制备了用乙二胺（EDA）官能化的合成的四苯基卟啉镁（MgTPP），该乙二胺负载在聚醚酰亚胺（PEI）纳米纤维上。评价了所开发的膜对潜在的CO ₂和PM _2.5捕集的能力。乙二胺，螯合剂被加载到纤维结构上; 引入的氨基悬垂物捕获了CO ₂分子有效。通过红外光谱揭示了结构证据。氨基修饰的MgTPP / PEI纳米纤维的平均直径为1.2–1.4μm，并具有411°C的高热稳定性。接触角的测量证明了过滤器的亲水性。纤维膜的高CO ₂和PM _2.5过滤能力分别为74％和81％，并且具有非零的粉尘负荷能力。最后，从统计学上证明了添加EDA对于CO ₂吸附的重要性。
