PURPOSE:To provide a catalyst for decomposition of NOx enabling decomposition of NOx contained in exhaust gas from the diesel engine of an automobile, etc., or various burners for an industrial furnace, etc., in which combustion with excess oxygen is carried out into harmless compds. without using ammonia. CONSTITUTION:One or more kinds of alkaline earth metals and/or silver is supported on a carrier such as gamma-alumina by a soln. impregnation method to obtain a catalyst and NOx in exhaust gas is decomposed with the catalyst while feeding hydrocarbon such as C3H8. |
