| 英文摘要 | promoted metal utilization capacity of zsm-5 zeolite has been achieved via the intracrystalline mesopores created by alkali treatment. the untreated and alkali-treated zn/zsm-5 catalysts were prepared by the conventional liquid ion exchange and impregnation methods. these catalysts were investigated by several techniques: n(2) adsorption-desorption, transmission electron microscopy, x-ray photoelectron spectroscopy, ammonia temperature-programmed desorption, and fourier transform infrared spectroscopy. compared with the untreated catalysts, the alkali-treated catalysts exhibited higher zn-loading in liquid ion exchange, better metal distribution and more lewis acid sites in impregnation, owing to the location of zn species in the created intracrystalline mesopores. the alkali-treated zn/zsm-5 catalysts displayed dramatically improved catalytic stability in 1-hexene aromatization. these findings show new potential for developing some advanced bifunctional metal-zeolite catalysts by a facile and low-cost method.
