No gas too small : A synthetic potassium gallosilicate natrolite with Si/Ga=1.28 (denoted PST‐1; see picture, Ga/Si gray, O red, K pink) was found to selectively adsorb small gases, especially H 2 , and hence to discriminate them from slightly larger molecules such as Ar or CO 2 . The remarkable ease of its dehydration and great (hydro)thermal stability make PST‐1 a potential candidate for fast, selective H 2 or He separation processes.
