Catalyst and method for removing NOX from combustion exhaust gas

A catalyst for removing NOx from a combustion exhaust gas, wherein the catalyst comprises an oxide of titanium, an oxide of molybdenum and/or tungsten, and an oxide of vanadium, wherein a ratio of V element to Ti element is not more than 2% by weight in terms of a weight percentage of V2O5/TiO2,

• the catalyst has a ratio of a pore volume in a range of pore diameter of not less than 500 A and not more than 3000 Å relative to a total pore volume of not less than 15% and not more than 40%, a ratio of a pore volume in a range of pore diameter of not less than 500 Å relative to the total pore volume of not less than 25% and not more than 50% and a ratio of a pore volume in a range of pore diameter of not less than 1000 Å relative to the total pore volume of not less than 10% and not more than 45% in a pore volume distribution in a range of pore diameter of not more than 105 Å.
