Sr2FeNi0.4Mo0.6O6-? Evolution for SOFC and SOEC Applications

Highlights Structural evolution of SrFeMoNiO (SFNM) is studied in various reduction conditions. XRD and TPR characterizations provides insights into the redox behavior of SFMN. Metals exsolution and the formation of a Ruddlesden-Popper (RP) are interdependent phenomena. Cathodic polarization causes metal nanoparticles to be covered by the RP phase. This unusual morphology increases the CO electroreduction activity into SOEC.
