| 英文摘要 | the coadsorption of cyclohexanone and oxygen on pt(lll) has been investigated by hreels and tds. at 205 k the presence of oxygen induces an "extra" red-shift of the c = o stretching of coadsorbed cyclohexanone. heating this coadsorbed surface from 205 to 250 k leads to further dehydrogenation to form intermediate species and to complete disappearance of the c = o stretching band. above 300 k, the molecule rings of dehydrogenation species cleave to form hydrocarbon fragments and co molecules which directly desorb into the vacuum or react with preadsorbed oxygen to produce co2 which leave the surface immediately. tds results provide further evidence that the preadsorbed oxygen promotes the decomposition of cyclohexanone. |
