Abstract:

Cobalt oxide exsolution as a result of reduction of A-site understoichiometric double perovskite Pr1-xBa1-xCo2O6-γ was found. The reasons for inconsistencies in the experimental data on oxygen content in PrBaCo2O6-δ reported by different authors were discussed. The step-like changes of the oxygen content of PrBaCo2O6-δ with pO2 in the temperature range 1023-1173 K were shown to correspond to reduction of exsolved Co3O4 to CoO. The defect structure analysis of PrBaCo2O6-δ was carried out using the conventional Kröger-Vink approach. The model proposed for the defect structure of PrBaCo2O6-δ was shown to coincide completely with available data on the oxygen content and crystal structure of this double perovskite. © The Royal Society of Chemistry 2016.
