1. A vanadium pentoxide-tungsten trioxide deNO_xing catalyst supported on an iron ion-exchanged titanium dioxide for selectively removing nitrogen oxides from stationary sources using ammonia or urea as a reducing agent, wherein the iron ion-exchanged titanium dioxide support is prepared by modifying and functionalizing the surface of a bare titanium dioxide, mixing with a precursor of iron ions, and then exchanging with the iron ions at a sublimation temperature of the precursor using an ion-exchange technique.
