325. 废弃聚对苯二甲酸乙二酯捕获二氧化碳
from 知为谁 · host 知为谁
该研究提出了一种创新方法，通过氨解反应将废弃的聚对苯二甲酸乙二醇酯 (PET) 塑料化学升级为二氧化碳 (CO2) 捕获材料。由此产生的双氨酰胺 (BAETA) 和低聚物，作为独立的有机固体材料，显示出高达每千克 3.4 摩尔的高 CO2 捕获能力。BAETA 具有出色的热稳定性和氧化稳定性，使其能够在高达 170°C 的高温下有效捕获来自烟道气或环境空气中的 CO2，并且可以在多个循环中重复使用。这种方法不仅解决了 PET 塑料废弃物的积累问题，还为实现负碳排放目标提供了一条有前景的、可规模化的途径。内容来源：https://www.science.org/doi/10.1126/sciadv.adv5906
