Abstract: This review highlights various aspects of current palladium membrane research and serves as a comprehensive bibliography covering palladium membrane preparation methods and applications. There are many promising uses for palladium membranes, although widespread use of the available technologies is constrained primarily by the high cost of palladium, lack of durability due to hydrogen embrittlement, and susceptibility to fouling. Various researchers in the field are tackling these problems and fabricating thinner palladium alloy composite membranes that better withstand contaminantion and thermal cycling. What has been accomplished to address these issues and the directions presently being explored are discussed.

Novel preparation of Pd/Vycor composite membranes
TL;DR: In this paper, the microstructure of the palladium film can be manipulated to yield both porous and dense films without altering the chemistry of the plating bath, and a new preparation technique which combines electroless plating and osmosis can be used to obtain both a high luster and smaller grain size.

Analysis of equilibrium shift in isothermal reactors with a permselective wall
Krishna Mohan,Rakesh Govind +1 more
TL;DR: In this article, a fundamental understanding of the behavior of a permselective wall (membrane reactors) in terms of design parameters (reactor length, membrane thickness); operating variables (pressure ratio, feed flow rate); physical properties (rate constant, permeability of fast gas, permselectivity, equilibrium constant); and flow patterns (recycle, cocurrent, countercurrent).

- 02 Dec 1987
TL;DR: An ultrathin, high-flux composite membrane for use in gas separation was proposed in this paper. But this membrane is not suitable for the purification of hydrogen gas, as it is not strong enough to handle hydrogen gas.

Ethylene, sulphur, and chlorine coadsorption on Pd(111): a theoretical study of poisoning and promotion
P.A. Gravil,Hervé Toulhoat +1 more
TL;DR: In this paper, first principles calculations for the coadsorption of hydrogen with sulphur and chlorine on Pd(111) were presented, and the presence of chlorine adatoms on the sulphur-poisoned surface was found to stabilise localised hydrogen adsorption.
