二氧化碳排放和塑料污染是两个主要的、大规模的、相互关联的环境挑战。尽管进行了密集的努力，但总体上仍然缺乏能够同时解决这两个问题的解决办法。释放塑料废物捕获二氧化碳的潜力将是发展循环经济和可持续未来的理想选择。在这项工作中，我们展示了使用聚丙烯掩膜作为前驱体来制造具有高表面积的氮和硫共掺杂碳纤维。这些材料在室温和1bar条件下具有4.8 mmol/g的CO2吸收率和高达78的CO2/N2选择性。本研究为将原纤维聚烯烃废弃物升级为多孔环境修复吸附剂提供了一种可行且可扩展的方法。
CO2 emission and plastic pollution represent two major, grand-scale, and interconnected environmental challenges. Despite intensive efforts, solutions that can concurrently address both are still in general lacking. Unlock the potential of plastic waste for CO2 capture would be ideal toward developing a circular economy and sustainable future. In this work, we demonstrate the use of polypropylene masks as the precursors for fabricating nitrogen and sulfur co-doped carbon fibers with high surface areas. These materials can exhibit an excellent CO2 uptake capacity of 4.8 mmol/g at room temperature and 1 bar and a high CO2/N2 selectivity up to 78. This work provides a feasible and scalable approach for upcycling of fibril polyolefin wastes to porous environmental remediation sorbents.
