Abstract
A catalyst material for nitrogen oxide reduction in flue gases in the presence of ammonia and a method for producing the same, includes adding vanadium oxide and at least one oxide of the elements from the group consisting of tungsten, phosphorous, sulfur, chromium, zirconium, magnesium, copper, cobalt, iron, and uranium to hydrothermal titanium oxide forming a mixture. The mixture is activated by grinding. A molybdenum component is admixed to the mixture. The mixture is subsequently temperature treated.
