Nitrogen oxides(NO x) are one of the main pollutants causing atmospheric pollution. Nitrogen oxides emitted from fixed sources such as industrial furnaces and coal-fired power plants and mobile sources such as motor vehicles have caused a series of damage to the ecological environment. Controlling and reducing NO x emission is a very difficult task at present. In the past decades, metal-organic frameworks(MOFs) have shown prominent heterogeneous catalytic activity due to their multiple active sites, large BET surface area, structural diversity and easy functionalization. These characteristics have attracted more and more attention to MOFs catalyst materials in the field of low-temperature industrial denitration in recent years. This review summarizes the application progress of MOFs materials in the low-temperature selective catalytic reduction of nitrogen oxides by ammonia. This review focuses on the application of MOFs materials of single and hybrid metals and the study of MOFs-derived composite catalysts. Finally, the current problems of MOFs in the field of low-temperature denitrification are proposed, and the development directions and prospects are prospected.
