Development 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 کاملCu2O/CuO Bilayered Composite as a High-Efficiency Photocathode for Photoelectrochemical Hydrogen Evolution Reaction
Solar powered hydrogen evolution reaction (HER) is one of the key reactions in solar-to-chemical energy conversion. It is desirable to develop photocathodic materials that exhibit high activity toward photoelectrochemical (PEC) HER at more positive potentials because a higher potential means a lower overpotential for HER. In this work, the Cu2O/CuO bilayered composites were prepared by a facile...
متن کاملPerformance and Long-Term Stability of Pd/PSS and Pd/Al2O3 Membranes for Hydrogen Separation
The present work is focused on the investigation of the performance and long-term stability of two composite palladium membranes under different operating conditions. One membrane (Pd/porous stainless steel (PSS)) is characterized by a ~10 µm-thick palladium layer on a porous stainless steel substrate, which is pretreated by means of surface modification and oxidation; the other membrane (Pd/Al...

Kinetics of NiO and NiCl2 Hydrogen Reduction as Precursors and Properties of Produced Ni/Al2O3 and Ni-Pd/Al2O3 Catalysts
The objects of this investigation were the comparative kinetic analysis of the NiO and NiCl2 reduction by hydrogen during an induction period and elimination of the calcination during the synthesis of Ni/Al2O3 catalysts. The effect of temperature and time on NiO and NiCl2 reduction degrees was studied. Avrami I equation was selected as the most favorable kinetic model and used to determine acti...
