【摘要】 高分子金属催化剂的性能,不仅与金属离子的种类有关,而且与高分子配体的结构有关。作者在以SiO₂负载的聚苯乙烯马来酸酐共聚物的苯胺氨解产物——钯单金属高分子催化剂（P—C₆H₅NH·Pd） 中引入少量的第一过渡金属离子,形成双金属高分子金属催化剂（P-C₆H₅NH·Pd·M）。研究结果表明,由于第一过渡金属离子的引入,使单金属高分子催化剂的催化加氢性能（活性、选择性和稳定性）得到了改善。而且发现,第一过渡金属离子的助催化作用与它的晶体场稳定化能（Crystal Field Stablization Energy,CFSE）有关。更多还原

【Abstract】 The catalytic properties of polymer metal catalysts strongly depend on the varioussort of metal ions and the structure of polymer ligands. In this thesis, a small amountof the first transition series ion was introduced into the mono-metal polymercatalyst-the complex of Pd and silica-supported synthetic product ofpolystyrene-maleic anhydride copolymer and aniline, to form bimetal polymer cata-lysts. The results showed that.the porperties of the bimetal polymer catalysts were moreimprovable than the mono-methal polymer catalysts for hydrogenation. Hence it wasfound that the promotion effect of the first transition series ions was qualitalively relat-ed to its crystal field stabilization energy (CFSE).更多还原
