Experimental study reveals changes in membrane structure during hydrogen separation, indicating performance under operational conditions.
The paper presents the results of studies of the structural-phase state and chemical composition of a membrane made of Pd–40 wt % Cu (Pd–52.8 at % Cu) alloy after its operation in an experimental hydrogen separation reactor for 20 hours at a temperature of 473–523 K. The methods of scanning and transmission electron microscopy, X-ray phase analysis and energy-dispersive spectroscopy A study of the evolution of the structural-phase state of the alloy under study was conducted with an analysis of the mechanisms of the observed processes.
