“…The quantity of this property by the Ce 3+ /Ce 4+ redox couple, which can be reversibly converted in the fluorite structure of CeO 2 , is called the oxygen storage capacity (OSC). In our previous studies, we confirmed that the oxygen reverse spillover caused by the interaction between the active metal Pt and the CeO 2 support and the excellent OSC of the CeO 2 support positively influenced the catalyst activity and sulfur tolerance in the WGS reaction [11][12][13][14][15]. It is noteworthy that various preparation parameters, such as reaction temperature, reaction time, precursor concentration, solvent, and pH, can be used to modify the characteristics of nanomaterials, including OSC, active metal dispersion, and redox properties.…”
