Microfabricated Palladium-based Membranes for Hydrogen Separation
An innovative process for the microfabrication of Pd-based membranes (Pd and Pd-Ag) on a <110> silicon wafer is presented. Pd-Ag alloy films containing 23wt% Ag are prepared by a dual-sputtering from pure Pd and Ag targets. In the first step, deep grooves are KOH etched in one side of a <110> oriented silicon wafer, leaving membranes with a thickness of ca. 50 μm. After Pd alloy deposition on t...
متن کاملDevelopment of Palladium-Alloy Membranes for Hydrogen Separation and Purification
This paper summarizes R&D activities and progress at NORAM Engineering and the University of British Columbia (UBC) on preparation and testing of thin palladium-based membranes and their applications. Most of these activities were carried out internally at NORAM, some jointly with UBC and their spin-off company, Membrane Reactor Technology (MRT) through a wide range of projects. Key results out...
متن کاملAdvances on High Temperature Pd-Based Membranes and Membrane Reactors for Hydrogen Purifcation and Production
Membrane technology applied in the chemical and energy industry has the potential to overcome many drawbacks of conventional technologies such as the need of large volume plants and large CO2 emissions. Recently, it has been reported that this technology might become more competitive...
متن کاملPalladium Alloys for Hydrogen Diffusion Membranes
Palladium holds a unique position among the metallic elements in being able to take into solution large quantities of hydrogen while simultaneously retaining a high degree of ductility. These attributes coupled with the high mobility or rate of diffusion of hydrogen in the lattice have been exploited in the use of palladium and subsequently of palladiumbased alloys as hydrogen diffusion membran...
متن کاملMicrofabrication of Palladium–Silver Alloy Membranes for Hydrogen Separation
In this paper, a process for the microfabrication of a wafer-scale palladium—silver alloy membrane (Pd–Ag) is presented. Pd–Ag alloy films containing 23 wt% Ag were prepared by co-sputtering from pure Pd and Ag targets. The films were deposited on the unetched side of a 110 -oriented silicon wafer in which deep grooves were etched in a concentrated KOH solution, leaving silicon membranes with a...
