description	The invention discloses a bimetal ferromanganese low-temperature catalyst for selective catalytic reduction (SCR) denitration as well as a preparation method and application of the catalyst, and belongs to the fields of atmospheric pollution control technology and environment-friendly catalytic materials. The catalyst for the SCR denitration is prepared by adopting Fe(NO3)3, Mn(NO3)2 and citric acid reagents as main raw materials and adopting a sol-gel method. The catalyst is obtained by the steps of performing magnetic stirring in a water bath, performing drying treatment and performing roasting in an air atmosphere, the catalyst uses MnOx and FeOx as active components, wherein a mass ratio of component element Mn to component element Fe to a carbon source in the catalyst is (0.05-0.2):(0.8-1.2):(0.5-2), and the catalyst has an operating temperature of 120-200 DEG C. According to the technical solution provided by the invention, the method provided by the invention can significantly improve the denitration e
