Novel Pd membrane: A composite palladium membrane for hydrogen separation has been fabricated by vacuum‐assisted electroless plating. Nanometer‐sized palladium grains are packed into a mesoporous γ‐alumina layer located on a macroporous alumina tubular support (see figure). The observed high resistance to hydrogen embrittlement is attributed to the novel membrane configuration and to size‐related effects of the palladium grains, and these materials may find use in gas‐separation membranes.
