Antimony-doped strontium cobalt oxide as promising cathode for low-temperature solid oxide fuel cell with excellent carbon dioxide tolerance

[Display omitted] •Antimony doping stabilizes cubic perovskite structure of SrCoO3-δ.•Remarkable oxygen reduction reaction activity is achieved.•The charge-transfer is confirmed as the rate-determining step.•Antimony doping enables perfect performance recovering from CO2 erosion.•The CO2 tolerance m...
