摘要
含氮分子筛作为一种新型的含骨架杂原子分子筛, 具有择形碱催化作用和酸碱双功能催化作用, 近年来引起了人们广泛的研究兴趣. 本文总结了微孔和介孔含氮分子筛在制备、表征和催化性能等方面的研究现状, 重点评述了氮化机理和理论计算在含氮分子筛研究中的应用, 并展望了含氮分子筛今后的研究方向.
Nitrogen-incorporated molecular sieves,a new family of hybrid molecular sieves,have drawn extensive attention because of their basic catalytic properties with shape selectivity and acid-basic bifunctional catalytic properties.In this paper,recent research and developments on the preparation,characterization,and catalytic application of nitrogen-incorporated molecular sieves are reviewed.Special emphasis is laid on the nitridation mechanism and theoretic calculations on nitrogen-incorporated molecular sieves.Finally,research and developments in the near future on nitrogen-incorporated molecular sieves are prospected.
