Dipeptide Crystals as Excellent Permselective Materials: Sequential Exclusion of Argon, Nitrogen, and Oxygen

摘要

Gas storage and gas separation using porous solids are important technologies that have attracted great attention because of their environmental and energetic applications. Highly porous materials, such as zeolites, silicate, and carbon-based materials have long-established specific applications. The key for new applications is the development of new frameworks. Advances in gas sorption capacities were achieved through the synthesis of materials such as metal-organic frameworks (MOFs), organic polymers, and micro-porous organic crystals. Recently, crystals formed by dipeptides were tested as adsorbents with significant results in hydrogen absorption and methane purification from carbon dioxide.
