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...
The electrochemical conversion of small organic molecules to value-added chemicals and hydrogen/electricity without CO2 emissions integrates efficient energy conversions (hydrogen or electricity) chemical productions in one reaction system, which is essentially competitive the carbon-neutral era. However, activity, stability, cost-effectiveness electrocatalysts, as well safety, durability, scalability devices, are still challenging for their industrial applications. In addition, a lack...
The performance of low-temperature solid-oxide fuel cells (LT-SOFCs) is heavily dependent on the electrocatalytic activity cathode toward oxygen reduction reaction (ORR).
Abstract The performance of Sr 2 FeMoO 6–σ double perovskites can be significantly enhanced by optimizing the ratio Fe/Mo as a promising electrode material for solid oxide fuel/electrolysis cells. However, intrinsic origin is still doubt improvement sluggish electrocatalytic reaction kinetics. Herein, their electronic structures are investigated partial replacement Mo with Fe ions. As content in 1+ x 1– O 6–δ increased, its oxidation state increases, which enhances metal–oxygen hybridization...
Hetero-structured DP/RP-SFCuM perovskite composites with exsolved Fe and Cu metallic nanoparticles exhibit excellent electrochemical performance in CO 2 electrolysis reactions for high solid oxide cells.
The in situ exsolution technique of nanoparticles has brought new opportunities for the utilization perovskite-based catalysts solid oxide cells. However, lack control over structural evolution host perovskites during promotion restricted architectural exploitation exsolution-facilitated perovskites. In this study, we strategically broke long-standing trade-off phenomenon between promoted and suppressed phase transition via B-site supplement, thus broadening scope perovskite materials. Using...
Exsolution of nanoparticles has become a prevalent technique for enhancing the catalytic activity perovskites carbon dioxide (CO2) electrolysis in solid oxide cells. However, potential negative impact phase evolution host perovskite on performance is often overlooked light overall enhancement from exsolution. Herein, we illustrate facile fluorine doping strategy to suppress transition Sr2Fe1.2Ni0.3Mo0.5O6–δ (SFN3M) during The experimental characterizations combined with density functional...
