摘  要:综述了采用后处理法和直接合成法制备的杂原子改性分子筛的优缺点及研究进展,并介绍了改进的直接合成法的特点及利用该方法制备的杂原子分子筛的应用情况。认为合成独特性质的杂原子层状分子筛已成为新的研究热点,而将分子筛与其他材料(如蒙脱土、氧化铝、水滑石和介孔氧化硅等)结合后形成复合材料也成为杂原子改性的一个方向。The characteristics and significance of heteroatom-containing zeolites were introduced, and two main methods for synthesizing the heteroatom-containing zeolites including Post-Synthetic treatment method and Direct Synthesis method were summarized in detail, and their merits and demerits were analyzed in this paper. The improved Direct Synthesis method and the application of the zeolites prepared through the method were discussed. The present research situation for the heteroatom- containing zeolites was reviewed, the synthesis of delaminated zeolites with unique properties would be a hot spot and composite materials formed by the integration of zeolites and other materials like montmorillonite, alumina, hydrotalcite and mesoporous silica would be one direction for the modification of zeolites with heteroatoms.
