| 英文摘要 | a series of zsm-5/zsm-11 co-crystalline zeolites with various compositions and morphologies were successfully synthesized via an organic template-free hydrothermal route and characterized by xrd, xrf, sem, nmr and n-2 adsorption/desorption technologies. the effects of raw materials and batch composition were investigated systematically. various silicon sources can be employed in the organic template-free synthesis of zsm-5/zsm-11 co-crystalline zeolite, however only a few types of aluminum sources are available. this organic template-free system is favorable to the aluminum-rich zeolite. with the increase of initial sio2/al2o3 ratio, the zsm-5 percentage in the zsm-5/zsm-11 co-crystalline zeolite increases as well as the crystal size, and especially the morphology of zsm-5/zsm-11 co-crystalline zeolite prepared from the colloidal silica-naalo2 solution system changes gradually from nano-rod aggregation, micro-spindle to single hexagon and then to twinned hexagon crystals. moreover, na+ and oh- in the initial materials can promote the nucleation of the zsm-5/zsm-11 co-crystalline zeolite significantly and are beneficial to the formation of crystals with relatively low length/width ratio, while k+ postpones the crystallization process seriously.
