Hollow fiber membranes from mixed‐conducting perovskites can separate oxygen selectively from gas mixtures. Wall thicknesses as low as 150 μm can be obtained by a wet spinning process, and oxygen fluxes are thereby obtained that are relevant for technical applications. In their Communication on page 2983 ff., H. Wang, J. Caro and co‐workers describe the complete decomposition of nitrous oxide with such membranes. This method offers new opportunities to reduce emissions of this greenhouse gas.
