The invention discloses a preparation method of a honeycomb-shaped SCR denitrification catalyst.The method includes the following steps of using KMnO4 and Mn(AC)2.4(H2O) as the precursors, adding citric acid and dispersing agent, obtaining precipitate through redox reaction, drying precipitate and grinding precipitate into powder, calcining powder in a muffle furnace, regrinding powder after calcining, filtering powder through an 80-mesh screen to obtain a powdery catalyst, evenly dispersing the powdery catalyst in silica sol, adding honeycomb-shaped cordierite ceramic with the preprocessed surface, taking out and drying a product after cordierite ceramic makes full contact with a silica sol solution, and conducting heat treatment in a microwave oven to obtain the honeycomb-shaped SCR denitrification catalyst.The denitrification catalyst has the denitrification efficiency of 50-99% at a temperature of 80-180 DEG C and an airspeed of 3000 h<-1> to 7000 h<-1> and has the denitrification efficiency of about 85% at the temperature of 120 DEG C.
