Inside Cover: Molecular Sieve Membrane: Supported Metal–Organic Framework with High Hydrogen Selectivity (Angew. Chem. Int. Ed. 3/2010)

Membranes derived from metal–organic frameworks present a new category of molecular sieves. As demonstrated by Y. Li., J. Caro et al. in their Communication on page 548 ff., a supported zeolitic imidazolate framework (ZIF-7) membrane exhibits high H2 selectivity by serving as a molecular sieve. The picture shows the synthesis of the ZIF-7 membrane which includes surface seeding and microwave-assisted solvothermal synthesis.
