In situ separation of plasma-generated species using metal-organic frameworks

Selectively extracting the desired reactive species from plasma could unlock various applications for plasma. This study uncovers the potential of metal-organic frameworks (MOFs) in selectively extracting plasma-generated species from the plasma environment. To demonstrate this, we utilized a zeolitic imidazolate frameworks-8 (ZIF-8) as the MOF separation membrane and Ar/C3H8 plasma. The ZIF-8 membrane proved effective in selectively extracting H-2 molecules produced from C3H8, as compared with the case without the ZIF-8.
