Combined electrochemical and catalytic study of Ba0.90Zr0.90Fe0.10O3 − δ (BZF10).
BZF10 is capable of catalyzing CO2 reduction to CO and O2.
Under moist CO, complex conduction and water-gas-shift reaction were observed.
Exposure to humidified H2 indicates n-type semi-conduction.
BZF10 was chemically and mechanically stable over all gases tested.
