A simple route for the manufacture of composites for hydrogen separation membranes

摘要

In this work we report on the manufacture and characterization of silver-BaCe_(0.5)Zr_(0.3)Y_(0.16)Zn_(0.04)O_(3-d) (BCZYZ) composites. We have prepared BCZYZ via a wet chemical route and studied the sintering properties by dilatometry. The powders were then coated with silver using Tollens’ reaction and sintered. The coated powders and sintered samples were analysed by XRD, SEM and the electrical properties were studied by impedance spectroscopy.
