In recent decades, anthropogenic industrial-based activities (i.e., energy production and its conveyance) has led to the emission of deleterious greenhouse gases such as CO2, H2S, and NO2 as an important environmental concern. Membrane-based gas separation processes have been currently of paramount attention in critical industrial applications such as purification, biogas recovery, water treatment, gas processing and H2 recovery. Polymeric nanocomposite membranes (PNM) have illustrated indisputable potential of utilization to mitigate the release of gaseous pollutants to the ecosystem and reduce their hazardous environmental effects. Incorporation of novel nanoparticles including activated carbon, nanofibers and carbon nanotubes have revolutionized the efficiency of polymeric membranes for gas separation. This review paper aims to present disparate applications of polymeric nanocomposite membranes for mitigating the emission of toxic/acidic gases to environment. Moreover, performance, applications and challenges towards the use of nanocomposite membranes are reviewed comprehensively and future perspectives towards their development in industrial applications are recommended. Finally, prevalent nanocomposite membranes for the separation of various gaseous mixtures are presented.

用于气体分离的聚合物纳米复合膜:性能、应用、限制和未来展望

近几十年来,基于人为的工业活动(即能源生产及其输送)已导致排放诸如CO 2、H 2 S 和NO 2等有害温室气体,这是一个重要的环境问题。目前,基于膜的气体分离工艺在净化、沼气回收、水处理、气体处理和 H 2等关键工业应用中备受关注恢复。聚合物纳米复合膜 (PNM) 已显示出无可争辩的利用潜力,可减轻气态污染物向生态系统的释放并减少其对环境的有害影响。包括活性炭、纳米纤维和碳纳米管在内的新型纳米颗粒的结合彻底改变了聚合物膜用于气体分离的效率。本综述旨在介绍聚合物纳米复合膜在减轻有毒/酸性气体排放到环境中的不同应用。此外,还全面回顾了纳米复合膜的性能、应用和挑战,并就其在工业应用中的发展提出了未来展望。最后,
