文摘
- •
A-site Nd-deficiency double perovskite material Nd0.96BaCo2O6−δ was successfully prepared.
- •
Nd0.96BaCo2O6−δ exhibits superior cathode catalytic activity compared to the stoichiometric material NdBaCo2O6−δ.
- •
The lowest area specific resistance is 0.043 Ω cm2 at 700 °C.
- •
The reaction rate limiting step is identified as a charge transfer process.
