Predicting Catalyst Performance From Pt/CeO2 Redispersion Kinetics

Details on the treatment conditions or experimental stage can be found in the Experimental section of the study. 201902_COox_PtCeO2c_Fig5FigS4 Contains end-of-pipe catalytic data (as concentrations) for Pt/CeO2 cubes under CO oxidation conditions. Multiple light-off and light-out cycles were performed consecutively and recorded in a single file. 201902_STEM_CeO2c_Fig1FigS1 Contains electron microscopy images of CeO2 cubes after preparation. 201902_STEM_PtCeO2c_FigS1 Contains electron microscopy images of Pt/CeO2 cubes after Pt impregnation. 201902_XAS_PtCeO2c_Fig1FigS3 Contains X-ray absorption spectra acquired for Pt/CeO2 cubes during reduction in 2% H2. 201904_ETEM_PtCeO2c_Redispersion_Fig2-4FigS6-S11 Contains a series of electron microscopy images of Pt/CeO2 cubes after reduction and during redispersion under oxidative conditions. 201904_ETEM_PtCeO2c_Reduction_FigS2 Contains ETEM images of Pt/CeO2 cubes after Pt impregnation and subsequent calcination at 300 °C in air (1 bar). 201904_STEM_PtCeO2c_ParticleSize_Fig1Fig5 Contains STEM images of Pt/CeO2 cubes after reduction at 500 °C in 17 mbar H2.

Files corresponding to X-ray Absorption Spectra and catalytic data are ASCII types. Electron microscopy images can be opened using FIJI (imagej.net/software/fiji/). For some files, the plug-in TIA reader (imagej.net/ij/plugins/tia-reader.html) is needed.
