Effect on OSC of high-temperature redox cycles

This behaviour is the opposite of that observed in pure ceria, for which the same thermochemical treatment leads to 

Given the practical relevance of this effect, much research effort has been devoted to clarifying its origin as well as its relation to the 

We should mention that assembling all the pieces in the puzzle has required information from techniques, which have just become fully available only recently, and also a detailed analysis of the chemical response of the oxides by very carefully designed experiments and, finally, reasoning far beyond a simple correlation between the bulk structure of the oxides and their redox response. 

3 Chemical and structural investigation of OSC changes after hi -temperature redox cycling 

From the above, it is fairly clear that a high temperature ( 1173K) reducing treatment is the triggering step that moves the fresh oxide
