qTP拓扑聚合物富勒烯纳米片膜实现选择性氢传输
Selective Hydrogen Transport Through Polymeric Fullerene Nanosheet Membranes
AI 导读
研究构建了由qTP拓扑中四向连接富勒烯笼构成的层状膜，面内孔道从约5.87 Å入口收敛至3.11 Å腰部，收缩区按尺寸筛分分子。在303.15 K、总进料压力100 kPa下分离等摩尔H2/CO2混合气，H2渗透率为3896 ± 107 GPU，H2/CO2分离因子为88.5 ± 5.9，并保持200 h运行稳定。该工作把拓扑编码的孔几何作为层状膜设计原则，将短选择性通路与埃级分子识别结合。
推荐理由
原文给出qTP拓扑富勒烯纳米片膜的面内孔道尺寸与H2/CO2分离数据，可据此判断这类层状膜的孔径设计思路。
创新点
不同于依赖堆叠层间距可变的层间通道，该膜利用qTP拓扑富勒烯笼在面内形成周期性埃级孔道，以固定收缩区实现尺寸筛分。
