Abstract

Xenon (Xe), the largest noble gas with nonradioactive isotopes, is difficult to contain in a solid matrix. This study demonstrates the trapping of Xe single atoms within subnanometer-sized silicate nanocages (NC) supported on metal powders. The Xe gas is first ionized using a plasma. The ions then enter the NC and get trapped in the solid upon gaining an electron from the metal support. This work presents the first demonstration of room-temperature trapping of Xe atoms in a high-surface-area material using a simple ionization method. This can lead to various practical applications such as Xe separation from air, improving the efficiency and safety of nuclear reactors, aiding in nuclear nonproliferation efforts, and producing medical isotopes, among many others.

氙(Xe)是具有非放射性同位素的最大惰性气体,很难包含在固体基质中。本研究展示了在亚纳米尺寸的金属粉末支撑的硅酸盐纳米笼(NC)中捕获Xe单原子。Xe气体首先用等离子体电离。离子然后进入NC并在从金属载体获得电子后被困在固体中。这项工作首次展示了使用简单的电离方法在高表面积材料中捕获Xe原子的室温。这可以导致各种实际应用,例如从空气中分离Xe,提高核反应堆的效率和安全性,帮助核不扩散努力,以及生产医用同位素等等。
