英文摘要	the novel cu-ir bimetallic catalysts with ceria modified silica supported were prepared via impregnation method for methanol decomposition. cu-ir/ceo2-sic2 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, h-2-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.
