Tailoring the Magnetic‐Field‐Assisted Oxygen Evolution Reaction Activity of Sr <sub>3</sub> YCo <sub>4</sub> O <sub> 12− <i>δ</i> </sub>
The room‐temperature ferromagnetic Sr 3 YCo 4 O 12− δ (314‐SYCO) provides an ideal platform for investigating magnetic‐field‐assisted catalytic performance. Herein, a series of 314‐SYCO polycrystals were synthesized via a sol–gel route by systematically varying the sintering temperature (800, 1000, and 120...
