"In this paper, we report simple and straightforward synthesis routes that enable fabrication of continuous ZIF-8 membrane layers on stainless steel and ceramic supports. The developed methods are based on various support surface modifications (i.e. 2-methylimidazole, zinc) and optimised in-situ solvothermal growth. These strategies result in strong bonding between the support and modifying species, consequently promoting heterogeneous nucleation and crystal growth. Synthesised membranes exhibit wellintergrown rhombic dodocahedral microstructures characterised by narrow particle size distribution and average crystal size of about 10-15 ?m (depending on the synthesis route). The repeatability of the methods was achieved via the control of the liquid/gas composition and the elimination of air bubbles present on the support surface. The former enabled method consistency, whilst the latter significantly improved the surface coverage. Finally, the CH4/CO2 separation performance of several scaled-up membranes was evaluated, revealing that the process is governed by the combination of surface and Knudsen diffusion."@en .
