Integrating Cation Disordering With Surface Tailoring via Sn/In Co-Doping for High-Performance Perovskite Cathode.
The development of stable, durable cathodes with high oxygen reduction reaction (ORR) activity remains a critical challenge in solid oxide fuel cell (SOFC) research. This work employs a Sn-In co-doping strategy to synthesize a cathode material with the nominal composition Ba(Co0.7Fe0.3)0.8(Sn0.5In0.5)0.2O3-δ. The co‑do...
