Perovskites with exsolved nanoparticles (P-eNs) have immense potentials for carbon dioxide (CO2) reduction in solid oxide electrolysis cell. Despite the recent achievements promoting B-site cation exsolution enhanced catalytic activities, unsatisfactory stability of P-eNs at high voltages greatly impedes their practical applications and this issue has not been elucidated. In study, we reveal that formation vacancies perovskite scaffold is major contributor to degradation P-eNs; then address by fine-regulating supplement reduced Sr2Fe1.3Ni0.2Mo0.5O6-δ using foreign Fe sources, achieving a robust prolonged performance. Furthermore, mechanism from perspective structure also proposed understand origins performance deterioration.
