Examining Operando Generated Ni-Based Alloy Nanomaterials as Fuel Electrodes in Solid Oxide Cells

Constructing nanostructure through exsolution has been demonstrated as an effective approach to producing electrode materials with superior performance and stability in the application of solid oxide cells (SOCs), primarily due excellent catalytic properties significantly enhanced offered by well-embedded nanoparticles that are exsolved from a supporting oxide. Here, we focus on investigating titanate perovskites Ni-Co alloy nanocatalysts fuel electrodes for SOCs, particularly operando generating these nanomaterials applying potential bias CO2 electrolysis operating conditions. Three compositions perovskite were examined, La0.43Ca0.37Ti0.94Ni0.06O3−δ (LCT-Ni6), La0.43Ca0.37Ti0.94Ni0.03Co0.03O3−δ (LCT-Ni3Co3), La0.43Ca0.37Ti0.90Ni0.05Co0.05O3−δ (LCT-Ni5Co5). Various techniques, including X-ray diffraction, thermogravimetric analysis, DC conductivity measurement, applied study crystal structure, reduction behavior, property, microstructure materials. SOCs fabricated evaluated, emphasis placed generation active electrochemical switching pure atmosphere, understanding linking their toward H2 cell.
