摘要：
Metal-supported zeolite catalysts have been widely used in the NH3 selective catalytic reduction (NH3-SCR) reactions due to their wide temperature window and good hydrothermal stability. In this review, the research progress in the structural characteristics, catalytic performance and reaction mechanism of Cu- and Fe-based zeolite catalysts in NH3-SCR was summarized. In addition, the application of density functional theory (DFT) calculation in clarifying the reaction mechanism of NH3-SCR was introduced. Finally, the reaction kinetics and the apparent kinetic parameters of different metal-based zeolite catalysts in NH3-SCR were compared and discussed. We hope this review could provide new ideas for the study of NH3-SCR reaction mechanism over metal-supported zeolite catalysts. © 2021, Science Press. All right reserved.
