Abstract
Provided is a nitrogen oxide removing denitrification catalyst having high durability against sulfur dioxide, a preparing method of the same, and a method for removing nitrogen oxide using the same. The denitrification catalyst is a quaternary denitrification catalyst containing vanadium-molybdenum-antimony-titania used in a selective catalytic reduction (SCR) reaction using an ammonia reductant to remove nitrogen oxides included in exhaust gases, antimony, molybdenum and vanadium are carried on a titania carrier, and molybdenum and vanadium are combined to be present in a form of a complex oxide (VMoO).
