摘要：
PrBa(Co1-xFex)2O5+d polymorphs (0.1 < x < 0.4, denoted as PBCF-x with Fe-doping level x) are reported and dual phase of cubic phase Pr0.5Ba0.5Co1_xFexO3_d and tetragonal phase PrBa(Co1-xFex)2O5+d are co-produced through an common sol-gel method. The co-generation of the dual-phases leads to the formation of abundant hetero-interfaces be-tween the neighboring crystal phases and the synergic effect demonstrates remarkably high oxygen adsorption and dissociation ability in the air. The density functional theory (DFT) calculation establishes that the existence of hetero-interfaces promotes oxygen ...
