Resumen: The use of thin film composites containing metal-organic frameworks (MOFs) as filler is of widespread interest for nanofiltration issues, since their thin selective layer allows a high permeation flow. The application of this kind of membranes for gas separation should provide a better permeance in comparison with other polymeric membranes and a reduction in the amount of MOF required for their fabrication. Here, the preparation of 50-100 nm thick polyamide flat membranes containing zeolitic imidazolate framework-8 (ZIF-8) nanoparticles is shown via interfacial polymerization, containing a lower amount of MOF (0.013 g m(-2) membrane) as compared to other membranes used for gas separation. The membranes are applied for H-2/CO2 separation at high temperatures and pressures, showing a stable performance at 180 degrees C for at least seven days. Outstanding separation values are 328 GPU of H-2 and a H-2/CO2 selectivity of 18.1 at 180 degrees C and 6 bar feed without transmembrane pressure. These membranes, also measurable without sweep gas, are highly suitable for industrial application.
