Abstract

Sintering behavior of Pt/γ-Al₂O₃, Pt/ZrO ₂ and Pt/CeO₂ catalyst was studied using an originally developed 3D sintering simulator. Experimental results were well reproduced. While Pt on the γ-Al₂O₃ sintered significantly, Pt on CeO₂ presented the highest stability against sintering. On the other hand, grain growth of supports was significant in the order; ZrO ₂ > CeO₂ > γ-Al₂O₃.
