摘 要: 鈀膜對氫氣有著優(yōu)異的滲透性和選擇性，在氫分離和膜催化反應(yīng)領(lǐng)域備受關(guān)注。將鈀膜直接沉積于多孔基體表面形成的鈀復(fù)合膜，具有厚度薄、力學(xué)強(qiáng)度高、氫滲透率高、成本低等優(yōu)點(diǎn)，但制膜難度較高。在各種制膜方法中，化學(xué)鍍法最為常用。在化學(xué)鍍制膜過程中，對鈀膜的質(zhì)量控制和缺陷修補(bǔ)工藝進(jìn)行了綜述，以期進(jìn)一步推動(dòng)高性能鈀復(fù)合膜的發(fā)展及應(yīng)用。

Abstract:Owing to the excellent permeability and permselectivity toward hydrogen, palladium membranes have attracted much attention in the fields of hydrogen separation and membrane catalytic reaction. Palladium membranes supported on porous substrate (i.e., composite palladium membranes) have many advantages, such as thin membrane thickness, robust mechanical strength, high H2-permeance and low cost, but the membrane preparation is challenging. Among various preparation methods, electroless plating is the most popular. Based on such process, the membrane quality control and defects repairing are summarized to push forward the development and application of composite palladium membranes.
Key words: porous substrate; composite palladium membrane; quality control; defects repairing; electroless plating
