A-site-induced structural transformation to improve OER activity and stability in SOEC

In this issue of Chem Catalysis, Bao and coworkers modify the electronic structures of CaxSr1-xCo0.7Fe0.3O3-δ (x = 0, 0.5, 1) by A-site-induced structural transformation, increasing the oxygen-related properties and electrical conductivity and thus promoting the anodic oxygen evolution reaction (OER) for solid oxide electrolysis cells (SOECs).
