| 英文摘要 | pt-cu/carbon black catalysts were prepared by an impregnation-reduction method followed by acid leaching. the structure and composition of pt-cu nanoparticles treated under different conditions were investigated by inductively coupled plasma atomic emission spectrometry, x-ray diffraction, and x-ray photoelectron spectroscopy. ptcu3 alloy formed upon annealing pt-cu/carbon black catalysts in h-2. acid leaching produced pt-cu nanoparticles consisting of pt-skeleton surface structure and ptcu3 alloy core. the pt-skeleton could be transformed to well-defined pt-skin structure through further annealing the leached pt-cu nanoparticles in h-2. decorating the pt-skin surfaces with fe oxide nanopatches resulted in enhanced reactivity in the preferential oxidation of co in excess h-2. the tri-component pt-cu-fe catalysts exhibited comparable activity to the bi-component pt-fe catalysts but used much less pt.
