| 英文摘要 | the variation of surface compositions on amorphous ni80.4w1.5p18.1 alloy by o-2 oxidation and h-2 reduction treatments have been studied by xps, ups and iss. it shows that addition of tungsten in the amorphous ni-p alloy leads to dramatic changes of the relating component distributions in the surface layers before and after these treatments. oxidation of a ni80.4w1.5p18.1 amorphous alloy in 1 bar of oxygen at 513 k caused a significant segregation of nickel in different oxide states at the surface. the subsequent reduction of the oxidized surface with i bar hydrogen at 553 k resulted in only a small portion of ni and p being reduced into elemental states, while most of them was found to combine to form a kind of nickel phosphate compound. on the other hand, under the same conditions, the oxidation and reduction of a ni80p20 alloy gave rise to metallic ni and elemental p as the predominate species on the alloy surface. the addition of w in the amorphous alloy might act as nuclei for a favorable formation of the phosphate structure which was proposed to be an active species for hydrogen-relating catalytic reactions.
