Abstract
The invention relates to a method for the fabrication of composite palladium or palladium alloy membranes. The surface of the porous ceramic substrate is modified with pencil to create a uniform and smooth layer, and the membrane is deposited via electroless plating. The advantages of the pencil modification are a reduction of the substrate surface roughness and a repair of substrate surface defects, which leads to a great improvement in the membrane uniformity and hydrogen permeation performances. This method is facile and economic, and it is especially effective on low-cost macroporous ceramic substrate materials. Furthermore, this method generates almost no pollution and therefore is environmentally benign.
