摘要
利用水热合成法制备了VSB-1,并研究了不同合成条件对VSB-1形貌的影响.研究表明,通过调节合成条件可以制备不同形貌的VSB-1.VSB-1的形貌可以从针状变成蘑菇状,并且VSB-1颗粒尺寸以及比表面积也发生了变化.针状VSB-1相比蘑菇状VSB-1具有更高的比表面积.同时研究表明,VSB-1具有较好的高温热稳定性,在400℃仍能保持蘑菇状形貌.
VSB-1was synthesized by hydrothermal method in various synthesis conditions,and the influences of the synthesis conditions on the morphology of VSB-1were studied.The results show that by adjusting the synthesis conditions,different morphologies of VSB-1 can be obtained.The morphology of VSB-1changes from a needle-like to mushroom-like shape and the diameter of the VSB-1also varies.The morphologies influence the surface areas of VSB-1.The needle-like VSB-1has a higher BET(Brunauer-Emmet-Teller)surface than that of mushroomlike VSB-1.Meanwhile,the results show that VSB-1has high thermal stability.
