On the tracks of surface dynamics of LaFeO3-based perovskites

LaFeO3-based mixed oxides of mostly ABO3 perovskite structure are promising materials for key surface redox processes, such as three-way catalysis (TWC) or oxygen reduction at solid oxide fuel cell (SOFC) cathode. By taking advantage of the versatility of the perovskite structure, it is possible to prepare modified oxides with drastically increased performances as compared to the parent LaFeO3. Here, we explore the effect of La deficiency on the dynamics of selvedge under model redox excitation. We show here the results of a unique combination of sample- and technique-based
