| 英文摘要 | nanofibrous suz-4 zeolite (nf) was synthesized for preparing the pt/hsuz-4 catalyst used in the selective catalytic reduction of nox by hydrogen (h-2-scr). the seed dissolution during the crystallization played an important role for the nanofibrous suz-4 formation. it was found that the zeolite nf is oriented along the 10-ring channels, and it has much more bronsted acid sites on its external surface compared with general suz-4 zeolite. consequently, pt primarily existed as the well-dispersed particles (similar to 5 nm) on the nf external surface for the pt/nf catalyst prepared by impregnation. in comparison with 0.1 wt.% pt/hzsm-5 as well as general 0.1 wt.% pt/hsuz-4, the 0.1 wt.% pt/nf catalyst gave much higher activity and n-2 selectivity in the h-2-scr. for identifying the pt ions in suz-4 zeolite channels, the band at 1652 cm(-1) ascribed to nitrous species adsorbed on the ions was proposed.
