•HAADF-STEM revealed atomically dispersed CeOx species in NM1-xCexO2/γ-Al2O3 catalysts.•CeOx species may order at the surface of γ-Al2O3 support.•Concentration of CeOx species increases after reduction treatment at high temperature.•Spreading of CeOx over alumina explains the amorphiztion of ceria observed by XRD.
