Title: Roles of reaction kinetics of CO 2 on a PrBaCo 2O 5.5+δ surfaces

A symmetric PBCO/YSZ/PBCO cell (where PBCO refers to PrBaCo 2O 5.5+δ, and YSZ to yttria stabilized zirconia) was designed and fabricated for the investigation of the catalytic nature and reaction kinetics of CO 2 on PBCO surfaces. The electrochemical impedance spectroscopy was employed to probe the CO 2 reaction behavior on the PBCO electrode. The symmetric equivalent circuit cell characterization reveals that the surface resistance of CO 2 on PBCO is only 30.2 Ω cm 2 and the maximum surface exchange coefficient k chem is 2.0 × 10 -4 cm s -1 at 1147 K, suggesting that PBCO can be an excellent candidate for CO 2 reduction.
