a Synthesized crystal of ZIF-62. b Melt-pressed agZIF-62 on Al-foil, which was made following c the temperature-time diagram for glass preparation. d Thin, large area annealed agZIF-62 glass sheets can be produced reproducible in larger quantities. e Manufactured agZIF-62 membranes with a thickness of 330 µm. f The membranes stabilized by silica-lime glass rings and epoxy resin for handling. g These free-standing agZIF-62 films were installed into our permeation cell and measured. h Schematic image of the gas permeation is highly selective for He, H2 and impenetrable by methane.
