Mo 2 C‐coated vanadium composites are presented as an example of a new class of metallic membranes for hydrogen separations. Unlike conventional platinum‐ group catalysts, Mo 2 C does not alloy with the bulk metal at temperatures >350 °C, allowing for operation without risk of embrittlement or loss of catalyst activity. Optimal permeabilities approach that of palladium, at a far lower cost.
