Abstract

Abstract: The effects of the second carrier, such as ZrO₂, TiO₂ and γ-Al₂O₃ on the thermal stability of combustion catalyst were studied by XRDand DTA.The results indicate that the phase change of γ-Al₂O₃(γ→α-Al₂O₃) as the first carrier is a main reason for descents of oxidation activity of catalysts, and the phase change of γ-Al₂O₃ was inhibited in the presence of ZrO₂.However, TiO₂ promoted the phase change of γ-Al₂O₃.

Key words: Catalytic oxidation, Palladium, Platinum, Second carrier
