Abstract:Uniform SUZ-4 zeolite nanofiber (about 12 x 1500 nm) was obtained for the first time. The SUZ-4 zeolite was synthesized by hydrothermal treatment of the initial aluminosilicate gel at 150 degrees C with the assistance of definite amount of special seed slurry while without additional use of template. It was found that morphology of the SUZ-4 zeolite synthesized can be simply controlled by the character of seed slurry that is mainly determined by the crystallization period in preparation. The seed slurry containing plenty of less stable SUZ-4 crystallites obtained by crystallizing the aluminosilicate gel (7.9 KOH:1.0 Al2O3:2.6 TEA-OH:21.2 SiO2:498.6 H2O) under rotation at 150 degrees C for 16h leads to the synthesis of nanofibrous SUZ-4. while that primarily containing stable SUZ-4 crystallites obtained by prolonged crystallization period leads to the synthesis of rod-like zeolite.
