摘要

Mo2C-coated vanadium composites are presented as an example of a new class of metallic membranes for hydrogen separations. Unlike conventional platinum-group catalysts, Mo2C does not alloy with the bulk metal at temperatures >350 degrees C, allowing operation without risk of embrittlement or loss of catalyst activity. Optimal permeabilities approach that of palladium, at a far lower cost.
