Abstract

In this work, we focus on investigating the titanate perovskites with exsolved Ni-Co alloy nanocatalysts as fuel electrode of solid oxide cells (SOCs), particularly on operando generating these nanomaterials via applying a potential bias in CO₂ electrolysis operating conditions. Three compositions of titanate perovskite were examined, including La_0.43Ca_0.37Ti_0.94Ni_0.06O_3-δ (LCT-Ni6), La_0.43Ca_0.37Ti_0.94Ni_0.03Co_0.03O_3-δ (LCT-Ni3Co3), and La_0.43Ca_0.37Ti_0.90Ni_0.05Co_0.05O_3-δ (LCT-Ni5Co5). Various techniques, including X-ray diffraction, thermogravimetric analysis, DC conductivity measurement etc., were applied to study the crystal structure, reduction behavior, conductivity property, and microstructure of these materials. SOCs with these titanate fuel electrodes were fabricated and evaluated, with emphasis placed on operando generation of active nanomaterials through electrochemical switching in pure CO₂ atmosphere, and on understanding the materials properties linking to their microstructure and performance towards CO₂electrolysis and H₂ fuel cell.
