| 英文摘要 | the hydrogen evolution reaction (her) on ni-p alloys was investigated experimentally and theoretically. first ni-p alloys with p content in the range from 5.8 to 10.0 wt% were prepared by electrodeposition. the best catalysis to the her was found on the ni-p alloys with p content of 6.0 wt% (10.8 at%). in order to understand the function of p element in ni-p amorphous alloys for the her, the density-functional theory (dft) method and front molecular orbital (fmo) theory were used to analyze the function of p element in ni-p amorphous alloys for the her. the research shows: it is easier for water molecule to get the first electron and form ni(n+1)-h and ni(n)p-h on ni(n+1) clusters than on ni(n)p clusters, but it is more difficult for water molecule to get the second electron from ni(n+-1)-h than ni(n)p-h. the strength of ni(n+1)-h bond is always greater than that of ni(n)p-h. it means it is more difficult for hydrogen evolutes from ni(n+1) clusters than ni(n)p clusters. regardless of which step among all steps of the her is the rate-control step, the ni-p alloys with p contents being in a range of 9.1-14.3 at% would be always good to the whole her.
