Novel Cu-Ir Bimet allic Catalysts Supported on CeO-2 Modified SiO2-

Abstract

Abstract: The novel Cu-Ir bimet allic catalysts with ceria modified silica supported were prepared via impregnation method for methanol decomposition. Cu-Ir/CeO₂^--SiO₂^- catalyst exhibited a higher catalytic activity and a better stability than Cu-Ir/SiO₂^- catalyst. After 10 h of reaction, the methanol conversion was still over 96% with ceria modified Cu-Ir/SiO₂^- catalyst, while that of Cu-Ir/SiO₂^- catalyst decreased to 39.1%. The catalyst samples were characterized by XPS, H₂-TPR, XRD and BET techniques. The addition of ceria to silica supported Cu-Ir catalyst could improve the dispersion and restrain the sintering of the active component.
