Abstract: Palladium-based membranes have been widely studied in terms of their use in hydrogen separation processes. The high permeability and selectivity of these membranes mean that they are suitable for a variety of applications, although these are limited by the high cost of the precious metal. In order to reduce the cost, several researchers have …
