To provide a catalyst for purifying a combustion exhaust gas and a method for purifying a combustion exhaust gas. The denitration catalyst used in a method for purifying a combustion exhaust gas of removing a nitrogen oxide in the exhaust gas by making the catalyst into contact with the combustion exhaust gas having an alcohol as a reducing agent added thereto, contains zeolite as a support having supported thereon a catalyst metal, in a powder X-ray diffraction (XRD) measurement of the denitration catalyst a ratio (relative peak intensity ratio) r=I/J of a height I of a diffraction peak at a diffraction angle (2θ) of from 7.8 to 10.0° and a height J of a diffraction peak at a diffraction angle (2θ) of from 28.0 to 31.0° being in a range of from 3.0 to 5.0.
