Proton segregation and space-charge at the BaZrO3 (0 0 1)/MgO (0 0 1) heterointerface

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1414887

Y-doped BaZrO3 (BZY) can be deposited epitaxially on MgO (0 0 1) and the considered interface serves as a model system for studying heterointerface properties of protonic conductors. In this study, the defect chemistry of the interface between ZrO2-terminated BaZrO3 (0 0 1) and MgO (0 0 1) was inves...

Interplay between propylene and H2S co-adsorption on the H2 flux characteristics of Pd-alloy membranes employed in propane dehydrogenation (PDH) processes

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1392664

The role of propylene and H2S exposure on Pd-Ag membranes was investigated by hydrogen flux measurements of a magnetron sputtered Pd77Ag23 film and first-principles calculations of hydrogen, sulfur and propylene adsorption on the membrane surface. Upon exposure to 10% propylene, the H2 flux was lowe...

Investigation of Pd-based membranes in propane dehydrogenation (PDH) processes

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1392662

Pd-based membranes have potential applicability in the PDH process to selectively remove hydrogen. In the current work, H2 flux values and coke formation kinetics applying representative gaseous feed mixtures under varying operating conditions are evaluated and modelled. From these experiments, it i...

The performance of Pd-Ag alloy membrane films under exposure to trace amounts of H2S

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1392657

In the current article we present the long-term performance of 10 μm-thick Pd77Ag23 membranes under the exposure to varying concentrations of H2S ranging from 5 ppb to 20 ppm at temperatures of 350 and 450 °C. Membranes are exposed to H2S during 265 hours followed by either a H2 flux recovery study,...
