形貌工程构建四元环孔道 ZIF 纳米片膜用于丙烯/丙烷分离
Morphology‐Engineered ZIF Nanosheet Membranes With 4‐Membered‐Ring Apertures for Propylene/Propane Separation
AI 导读
研究团队通过形貌工程将 ZIF 纳米颗粒的孔道各向异性转化为二维纳米片中选择性暴露的四元环孔道，并组装成高度取向的 2D ZIF 混合基质膜。
推荐理由
通过形貌工程把 ZIF 纳米片的四元环孔道定向暴露并平行于气体传输方向，给出了取向与分离性能的直接对应关系。
创新点
把 ZIF 纳米颗粒固有的孔道各向异性转化为二维纳米片中定向暴露的四元环孔道，并用剪切流预取向使孔道平行于传输方向，从而在 MMM 中同时调控孔道可及性与取向。
