CREATION OF HYDROGEN - SELECTIVE TUBULAR COMPOSITE MEMBRANES BASED ON Pd-ALLOYS: I. IMPROVEMENT OF CERAMIC SUPPORT WITH Ni LAYER DEPOSITION
alternative to expensive dense Pd-membranes are composite membranes with porous ceramic supports allowing considerable reduction of Pd (Pd alloy) layer thickness and membrane cost and ensuring at the same time enhanced permeability and good operating ability. However commercially available porous materials can not be directly used. The development of tubular composite α-Al2O3 -based supports for Pd-containing metal membrane is reported. Their distinction consists in using metal nickel, which is analog of palladium in many respects, for the modification of the porous structure of ceramic substrates. Magnetron sputtering is the most perspective for support modification with Ni layer and the following Pd-thin film deposition.
