dc.description.abstract | Solid oxide cells (SOCs) are pivotal in electrochemical energy conversion technologies, but their operation at high temperatures necessitates the development of efficient and durable electro-catalysts. Herein, a novel electro-catalyst composed of Pt3Ni alloy nanoparticles exsolved on oxygen-deficient PrBaMn1.8Pt0.15Ni0.05O5+delta layered perovskite oxides is presented. This design addresses the critical problem of nanoparticle agglomeration at high temperatures, a major hurdle for SOCs. The atomic-scale mechanisms of oxygen vacancy formation and hydrogen evolution reaction kinetics in the material are unraveled through density functional theory calculations. A unique finding of this work is the formation of a core-shell structure during water electrolysis, simultaneously enhancing the electrochemical performance and operational durability in both fuel cell and electrolysis cell modes. This study not only strengthens the potential of Pt-Ni alloy nanoparticles as efficient electro-catalysts for SOCs, but also opens up avenues for future exploration in energy-related fields. | - |
