摘　　要：采用淀粉辅助水热合成方法,得到了特殊的一维链状纯硅沸石分子筛。结果表明在淀粉作用下,多个分子筛晶粒在晶轴b方向的表面之间存在强的相互作用使得分子筛晶粒沿此方向自组织成一维链状结构,所得材料非常均匀,乙醇的加入会使得这些一维聚集体的侧向团聚增加。A synthetic approach under assistance of starch has been developed to obtain pure silica zeolite with ID chain-like microarchitectures most probably by a self-assembly process of zeolite crystalline building units along the b axis of crystals. The products are very uniform. The ethanol together with starch in the synthetic system causes more conglomeration of zeolite crystals, even at the lateral directions, but less selective to chain-like structure.
