Abstract

An ultrathin and continuous ZIF-8 membrane as thin as ∼550 nm was fabricated via a spatially confined contra-diffusion process, in which a nanoporous network film is utilized as an interlayer mediator to control the nucleation and growth of ZIF-8 crystals. The membrane exhibits a high H2 permeance up to 6.31 × 10−7 mol m−2 s−1 pa−1 and simultaneously maintains a high ideal selectivity of 43 for H2/CO2.
