A novel electroless plating procedure has been proposed to prepare palladium/ceramic composite membrane. In general, an electroless plating process consists of activation of a substrate and deposition of palladium on it. In a conventional electroless process, the activation of a substrate is performed by the oxidationreduction of Pd(Ⅱ) with Sn(Ⅱ).

A novel electroless plating procedure has been proposed to prepare palladium/ceramic composite membrane. In general, an electroless plating process consists of activation of a substrate and deposition of palladium on it. In a conventional electroless process, the activation of a substrate is performed by the oxidationreduction of Pd(Ⅱ) with Sn(Ⅱ). However, in this work the solgel process with Pd(Ⅱ)modified sol was employed to produce an activated substrate. Thus the modified electroless plating procedure becomes more convenient, and Snfree palladium composite membrane can be realized using the novel method. Pure gas permeation experiment shows that the resulting membrane exhibited a permeation rate of 005~24 cm3/(cm2·s) and a H2selectivity (H2/N2 ratio) of 20~130 at 314~450℃ and 002~010 MPa transmembrane pressure drop.

提出钯金属复合膜制备的一种新化学镀饰过程,由衬底活化和金属自催化沉积两个主要步骤构成.一般的化学镀饰过程用Pd(Ⅱ)/Sn(Ⅱ)溶液的氧化还原反应活化目标衬底;新的化学镀饰过程是应用溶胶-凝胶技术活化目标衬底,从而明显地简化了镀饰过程.用新的化学镀饰过程制得的钯金属复合膜避免了Sn杂质;在温度314~450℃和膜两侧的压力差002~010MPa的实验条件下,对氢的选择性(氢氮分离系数)为20~130,氢的渗透速率为005~24cm3/(cm2·s).

The composite materials of molecular sieves film on the surface of metal substrates would find wide applications as they have excellent properties. In the present paper, ZSM-5 film was prepared on the surface of stainless steel substrate by hydrothermal method, and the effect of baking process on the film-substrate cohesion was examined by means of SEM and scratch test. The results of the analyses showed that the film-substrate cohesion was significantly improved by the baking process.
