摘　　要：这是一篇材料学领域的论文。采用胶体导向剂与Fe_(3)O_(4)制备了磁性LSX分子筛原粉,经银离子交换与水合肼还原后生成了含银原子的磁性LSX分子筛,利用扫描电镜、振动样品磁强计、X衍射分析仪、光电子能谱仪、比表面吸附仪对样品的表面形貌、磁性、物相结构、元素组成与比表面积进行了分析表征,结果表明磁性LSX分子筛为LSX分子筛与Fe_(3)O_(4)的复合材料,微孔比表面积为679.38 m^(2)/g,合成时胶体导向剂较佳加入量0.5%,磁性随Fe_(3)O_(4)加入量增加而增大,经银交换后与水合肼还原后的磁性LSX分子筛,比表面积减少。This is an article in the field of materials science.Magnetic LSX molecular sieves were prepared by colloidal directing agent and Fe_(3)O_(4).After silver ion exchange and hydrazine hydrate reduction,magnetic LSX molecular sieves containing silver atoms were prepared,the surface morphology,magnetic properties,phase structure,elemental composition and specific surface area of the samples were characterized by scanning electron microscopy,vibrating sample magnetometer,X-ray diffraction analyzer,photoelectron spectroscopy and specific surface adsorption instrument.The results showed that magnetic LSX molecular sieve is the composite material of LSX molecular sieve and Fe_(3)O_(4).The micropore specific surface area was 679.38 m^(2)/g.The optimum dosage of colloidal guide agent was 0.5%.The magnetic properties increased with the increase of Fe_(3)O_(4) content.The specific surface area of magnetic LSX molecular sieve reduced after silver exchange with hydrazine hydrate.
