Developing of Ethylene Glycol as a New Reducing Agent for Preparation of Pd-Ag/PSS Composite Membrane for Hydrogen Separation abstract

In the present work, for the first time, a palladium-silver membrane has been prepared by electroless plating on the surface of a porous stainless steel disk by using ethylene glycol as a new reducing agent and polyol process. The reducing action of ethylene-glycol in the presence of PVP as a protecting surface agent produces a membrane with finely divided powder and nano-sized pores. Furthermore, the hydrogen separation ability of the membrane confirmed that the membrane with Pd77Ag23 is highly selective towards hydrogen compared to other prepared membranes. This is mainly related to the formation of dense and homogenous microstructure of the coating. Moreover, according to Graham’s law, the tests showed that hydrogen purity rises by increasing the applying temperature.
