“…Metal composite membrane is becoming a promising choice for hydrogen separation, where recent efforts to increase the hydrogen permeation rates have led to the development of Pd-based composite membranes. Composite membranes with porous supports allow the considerable reduction of Pd (Pd alloy) layer thickness and membrane cost and at the same time ensure the enhanced permeability and good operating ability [1]. Palladium membranes were developed because of their high hydrogen permselectivity.…”

In this work, the potential of utilizing the porous alumina ceramic membrane coated with palladium as a hydrogen permselective membrane has been studied. The ceramic membrane is characterized by high permeability but at low hydrogen selectivity. In order to increase the pure hydrogen selectivity and to obtain high hydrogen yield on the ceramic membrane, palladium was coated on the alumina membrane surface. Such an arrangement would also enable the ceramic membrane to be operated at higher temperature. The preparation of the palladium coated ceramic membrane was carried out using combine sol-gel process and the electroless plating technique. The effect of combine sol-gel process with electroless plating towards deposits morphology, hydrogen permeability, and hydrogen permselectivity were analysed. The thickness and morphology of the α- Alumina and Pd composite membranes were analysed using a scanning electron microscopy (SEM) and atomic force microscopy (AFM).
