The development of new membranes with high H separation performance under industrially relevant conditions (high temperatures and pressures) is of primary importance. For instance, these membranes may facilitate the implementation of energy-efficient precombustion CO capture or reduce energy intensity in other industrial processes such as ammonia synthesis. We report a facile synthetic protocol based on interfacial polymerization for the fabrication of supported benzimidazole-linked polymer membranes that display an unprecedented H/CO selectivity (up to 40) at 423 K together with high-pressure resistance and long-term stability (>800 hours in the presence of water vapor).
开发在工业相关条件（高温和高压）下具有高氢分离性能的新型膜至关重要。例如，这些膜可促进高效的燃烧前二氧化碳捕集的实施，或降低其他工业过程（如氨合成）中的能源强度。我们报道了一种基于界面聚合的简便合成方法，用于制备负载型苯并咪唑连接聚合物膜，该膜在423K时表现出前所未有的氢/一氧化碳选择性（高达40），同时具有耐压性和长期稳定性（在有水蒸气存在的情况下超过800小时）。
