A highly efficient and stable perovskite cathode with in situ exsolved NiFe alloy nanoparticles for CO₂ electrolysis

Abstract

Perovskite structured oxides are promising candidate cathode materials for solid oxide electrolysis cells (SOECs) due to their better redox stability and coking resistance than the nickel-yttria stabilized zirconia. The present...

In Situ Growth of Ru/RuO2 Nanoparticle-Modified (PrBa)0.95Mn1.9Ru0.1O5+δ as a High-Performance Electrode for Symmetrical Solid Oxide Fuel Cells

“…The infiltration and impregnation techniques are traditional methods to introduce nanosized catalysts. , However, these surface-decorated techniques have several inherent drawbacks, such as complicated and time-consuming processing procedures, deterioration and agglomeration of nanoparticles occurring in a high temperature, and poor controllability over the size and distribution of nanoparticles. , Recently, a promising surface-decorated strategy via in situ growth has been applied to fabricate perovskite-type materials with catalytically active metallic nanoparticles . In this process, perovskite is substituted partially by transition metal atoms in the B site, which can exsolve from the crystal lattice, such as Co, Fe, and Ru .…”
