As many countries in the world are paying increasing attention to air quality, reducing the concentration of pollutants in the air, protecting human health and improving the ecological environment have become problems that need to be solved urgently. This paper describes how ceria and cobalt [email protected] (CeO₂/Co₃O₄@PAN) nanofiber membranes are produced using electrospinning technology, which have broad applications for the removal of air pollutants. Results show that CeO₂/Co₃O₄@PAN has high electrostatic attraction to particulate matter (PM). CeO₂/Co₃O₄@PAN membranes show better mechanical properties, thermal stability and air-purification performance than pure PAN membranes. Nanofiber membranes with 5 wt% of CeO₂/Co₃O₄ have excellent removal efficiency: 93.4% and 94.5% for PM_2.5 and PM₁₀, respectively, and 96.2% and 98% for formaldehyde and total volatile organic compounds, respectively. They also show low pressure drops, high stability and good recyclability. This work shows that they are promising candidates as highly stable, recyclable and efficient agents for the removal of air pollutants.

随着世界上许多国家对空气质量的日益重视，降低空气中污染物浓度、保护人类健康、改善生态环境已成为亟待解决的问题。本文介绍了如何使用静电纺丝技术生产氧化铈和钴 [电子邮件保护] (CeO ₂ /Co ₃ O ₄ @PAN) 纳米纤维膜，该技术在去除空气污染物方面具有广泛的应用。结果表明，CeO ₂ /Co ₃ O ₄ @PAN 对颗粒物 (PM) 具有高静电吸引力。CeO ₂ /Co ₃ O ₄@PAN 膜显示出比纯 PAN 膜更好的机械性能、热稳定性和空气净化性能。含有 5 wt% CeO ₂ /Co ₃ O _{4 的}纳米纤维膜具有出色的去除效率：PM _2.5和 PM ₁₀分别为 93.4% 和 94.5 %，甲醛和总挥发性有机化合物分别为 96.2% 和 98%。它们还表现出低压降、高稳定性和良好的可回收性。这项工作表明，它们作为高度稳定、可回收和高效的空气污染物去除剂是很有前途的候选者。
