Abstract: 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.

Key words: nitrogen-incorporated molecular sieve, surface acid/basic property, nitrogen content, nitridation mechanism, catalytic property, theoretical calculation
