| 英文摘要 | two types of fe-containing pt/kl catalysts were prepared, characterized and examined using an n-hexane aromatization reaction. pt/fekl contained framework fe, which was incorporated through hydrothermal synthesis, while pt-fe/kl contained non-framework fe, which was introduced through impregnation. the differences between the framework and non-framework fe were examined using xrd, ft-ir and mossbauer spectroscopy. pt dispersion and reducibility as well as the electronic states of the fe and pt particles were detected using h-2-chemisorption, h-2-tpr and xps, respectively. with the non-framework fe, an electron-rich platinum species (pt delta-) formed after reduction. with the framework fe, an electron-deficient platinum species (pt delta+) was detected. the n-hexane aromatization results from adding 0.3 wt% non-framework fe include conversion after 3.5 h on stream at 450 degrees c, h-2/n-hexane =3.0 (mole ratio) and 3 h(-1) whsv over the pt-fe/kl, which was maintained at 77%; these values are greater than the 41% pt/kl and 25% pt/fekl. the pt-fe/kl benzene selectivity was 89%, which is also greater than the 83% pt/kl and 53% pt/fekl. we discuss the effect of fe on the pt particle states and the relationship between the pt states and catalyst activity.
