| 英文摘要 | the catalysts derived from the reduction of intrazeolite pt carbonyl clusters [pt-12(co)(24)](2-)/nay and [pt-9(co)(18)](2-)/nay were characterized by exafs and chemisorption techniques. exafs analysis gave rpt-pt=2.74 angstrom, c.n.=4.2 for pt-12/nay and rpt-pt=2.74 angstrom, c.n.=3.8 for pt-9/nay, while the chemisorption of h-2 and co gave h/pt=1.26, co/pt=0.69 and h/pt=1.24, co/pt=1.26, co/pt=0.69 and h/pt=1.24, co/pt=0.64 for pt-12/nay and pt9/nay respectively. compared with the results of pt/al2o3, it is concluded that highly dispersed pt/nay catalysts were derived from the intrazeolite pt carbonyl clusters. because of the structureal changes of reduced pt carbonyl clusters, the recarbonylation of pt-12/nay and pt-9/nay can not regenerate the same pt carbonyl clusters as their precursors. |
