A real‐time observation of the redispersion behavior of sintered Pt on ceria‐based oxide was made possible by in‐situ time‐resolved Turbo‐XAS in fluorescence mode. 2 wt% Pt/Ce‐Zr‐Y mixed oxide samples were prepared, and then treated under an aging condition. The average Pt particle size measured by CO absorption method after aging was 7 nm. Redispersion treatments of the previously aged catalyst were carried out at 600°C within an in‐situ XAS cell in a cyclical flow of reducing/oxidizing gases. Pt L3‐edge XANES spectra were collected every 1.1 second under in‐situ conditions. From a change in the XANES spectra, we observed that the Pt particle size of the aged catalyst decreased from 7 to 5 nm after 60 seconds and then to 3 nm after 1000 seconds.
