A proportion of NO 2 is large exhaust gas, in particular sufficient denitration performance NO 2 / NO ratio in the exhaust gas is 1 or more conditions, i.e. nitrogen oxide, which can maintain a high removal rate of nitrogen oxide Provided are a catalyst for removing an object, a molded catalyst product, and an exhaust gas treatment method. In catalyst for removing nitrogen oxides for denitrating exhaust gas containing a high nitrogen oxides content of the A NO 2, as a component for reducing the NO 2 to NO, copper oxide, chromium oxide, and It contains at least one oxide of iron oxide, and contains titanium oxide, tungsten oxide, and vanadium oxide as components for reducing NO to N 2 .
