- •
In thermal aging, grown particles with Pt/Pd core and PdO shell formed.
- •
Al2(SO4)3 formed near small PtPd particles during S-treatment.
- •
With grown particles, Pt/Pd core + PdO shell, Al2(SO4)3 formed randomly in catalyst.
- •
Combined morphological changes and Al2(SO4)3 formation deactivated catalyst.
