The invention discloses a low temperature NH3-SCR denitration catalyst for a flue gas with low water vapor content. The catalyst is an oxide prepared by an impregnation method with TiO2 as a carrier loaded with Mn, Ce and Nb. The invention also discloses a preparation process of the catalyst. A preparation process of the catalyst is simple and easy to operate. The addition of Nb increases denitration performance of the catalyst for the flue gas with water vapor content as high as 12% and SO2 content of 1,000 ppm. The denitration rate at a temperature of 160 DEG C and in presence of 12% of water vapor and 1,000 ppm of SO2 can reach over 80%.
