dc.description.abstract[EN] Solid oxide electrochemical cells (SOCs) benefit from exsolution-based electrocatalyst design, where nanoparticles anchored in perovskites enhance stability and activity. Two of the most transformative features of this technology are the ability to engineer multielemental alloy nanoparticles for tailored catalysis and the potential for in situ catalyst regeneration through redox-driven redissolution. However, the fundamental mechanisms governing these processes in complex, multicomponent systems remain poorly understood. In this work, the simultaneous exsolution of Fe, Ni, Co, and Cu from the fuel electrode material Sr2Fe1.2Co0.1Ni0.1Cu0.1Mo0.5O6-delta was investigated using in situ powder neutron diffraction and synchrotron-based near-ambient-pressure X-ray photoelectron spectroscopy (NAP-XPS), combined with advanced electron microscopy to capture morphological evolution. At 700 degrees C, Cu-rich nanoparticles dominate, consistent with Ellingham reducibility trends; however, higher temperatures favor the formation of Fe-enriched alloys, driven by the high availability of Fe cations. Conversely, prolonged reduction promotes the formation of phase-separated Janus-type nanoparticles, primarily due to Fe-Cu immiscibility. Interestingly, redox cycling tests revealed that nanoparticle composition dictates redissolution capacity. While homogeneous alloys exhibited total redissolution into the perovskite backbone and subsequent re-exsolution, Janus-type nanoparticles underwent irreversible transformation into pyramidal NiO nanoparticles via intermediate cubic mixed oxide structures during air exposure. These findings elucidate how temperature, time, and elemental composition govern exsolved nanoparticle chemistry, morphology, and regeneration, establishing design principles for inducing multimetal exsolution in complex oxides toward enhanced electrocatalytic performance in energy conversion technologies.es_ES

dc.description.sponsorshipFinancial support by Generalitat Valenciana (CIPROM/2022/10) and by the Spanish Ministry of Science and Innovation (PID2022-139663OB-100 and CEX2021-001230-S) is gratefully acknowledged. These grants were funded by MCIN/AEI/10.13039/501100011033. We thank the financial support of the Helmholtz Initiative and Networking Fund through the German Federal Ministry of Education and Research (Bundesministerium fur Bildung und Forschung, BMBF) under Grant No. 03EW0015B (CatLab). These experiments were performed at BL24-CIRCE (proposal number 2024088545) beamlines at ALBA Synchrotron with the collaboration of ALBA staff. The authors wish to express their gratitude to the Institut Laue-Langevin (ILL) and the staff at D1B for making all facilities available for neutron diffraction experiments (Experiment No.CRG-2991).
