Incorporation of heteroatoms into the framework of zeolites has become a significant strategy to improve their performance in catalysis and adsorption, because the obtained heteroatom zeolites exhibit quite different properties from the conventional aluminosilicate zeolites in aspects of surface acidity, pore structures, particle size and so on. In this review, the progress on the heteroatom zeolites including their synthesis and application is highlighted. First, the recent advance on the design and synthesis of different heteroatom zeolites is summarized. Special emphasis is placed on the introduction and comparison of three typical methods, including the direct synthesis, post synthesis and improved direct synthesis, for the traditional heteroatom zeolites (such as TS-1, Sn-MFI, Sn-β) and newly-reported heteroatom zeolites (such as W-MFI, Mo-MFI). According to their intrinsic characteristics, the application of heteroatom zeolites in diverse fields, such as production of fine chemicals, air pollution control and biomass conversion is then discussed. Finally, the challenges and perspective on the future development of heteroatom zeolites in low-cost preparation and practical application are proposed.

新一轮课程改革铺天盖地席卷而来。以一支粉笔、一块黑板教了十几年语文的我,不知不觉中走进了语文课改实践中来。初中语文课堂教学由原来的教师讲授、学生默字以及读书、背书千篇一律的传统课堂向小组合作探究的新型课堂模式转变。由原来的教师为中心向以学生为主体教师为主导的课堂模式转变。  自我校课堂改革全面推进以来,我们的语文课堂也发生了翻天覆地的变化。在语文课堂改革前进的道路上摸爬滚打的我,困惑过、迷惘过,走
