| 英文摘要 | a set of bimetallic pt-ru catalysts prepared by co-impregnation of carbon black with ruthenium(iii) chloride hydrate and hydrogen hexachloroplatinate(iv) hydrate were investigated by temperature-programmed reduction (tpr), chemisorption of hydrogen, transmission electron microscopy (tem), microcalorimetry of adsorbed co and a structure-sensitive reaction (n-hexane conversion). the results showed that the volumetric capacities for co and h-2 adsorption is influenced in the bimetallic pt-ru catalysts by the formation of a pt-ru alloy. the n-hexane reaction revealed that the reaction mechanism for the pure pt catalyst mainly occurs via cyclic isomerization and aromatization due to the presence of bigger pt surface ensembles, whereas the pt-ru catalysts exhibited predominantly bond-shift isomerization by the diluting effect of ru metal addition. the differential heats of co chemisorption on pt-ru catalysts fell between the two monometallic pt and ru catalysts extremes.
