Pr and Mo Co‐Doped SrFeO_3–δ as an Efficient Cathode for Pure CO₂ Reduction Reaction in a Solid Oxide Electrolysis Cell

Abstract

The development of highly active and stable cathodes for carbon dioxide reduction reaction (CO2RR) is important for commercialization of energy conversion devices. Metallic nanoparticles in situ exsolved from parent oxide can not only greatly improve the stability of the cathode, but also efficiently boost CO2RR via a solid oxide electrolysis cell.

Novel Perovskite Oxide Hybrid Nanofibers Embedded with Nanocatalysts for Highly Efficient and Durable Electrodes in Direct CO2 Electrolysis

“…S17 ). Figure 5 d and Table 2 compare these values with various perovskite-based fuel electrodes reported in the literature as a function of temperature [ 1 , 3 , 4 , 6 , 18 , 46 , 58 , 59 ], where the H-LSCFP cell significantly outperformed state-of-the-art ceramic fuel electrodes for CO 2 -SOEC at all tested temperatures. To validate the high performance of the H-LSCFP cell, we conducted multiple runs of the identical experiment using different H-LSCFP cells, thus confirming the robustness and reproducibility of the reported results (Fig.…”
