    Abstract: PURPOSE: A catalyst for selective reduction of nitric oxide within exhaust gas containing rare earth metal and a manufacturing method thereof are provided to eliminate nitric oxide within exhaust gas of hydro-thermal treatment former and post treatment in the high temperature by using rare earth metal as co-catalyst and by using Mn and Fe as active component and zeolite as carrier. CONSTITUTION: The catalyst for the selective reduction of the nitric oxide within the exhaust gas containing the rare earth metal is immersed in the zeolite carrier. The catalyst contains more than one kind of manganic compound, and the iron compound selected from the rare earth metal. The co-catalyst component contains 4~40 weight% based of the standard of catalyst of total 100 weight of the rare earth metal and manganese and iron. The manganese contains 10~60 weight%. The iron contains 4~40 weight%. The zeolite is included in 20~200 parts by weight. The catalyst has the reduction activity capability of the nitric oxide of 80~100% in the reaction temperature of 200~400 °C after the hydro-thermal treatment. The reduction reaction of catalyst uses the element (Urea) or the ammonia (NH3) as the reducing agent.

    Abstract: The present invention relates to a perovskite catalyst for NO oxidation and a manufacturing method thereof and, in particular, to a perovskite catalyst for NO oxidation and a manufacturing method thereof capable of accelerating the usage of the perovskite catalyst for NO oxidation and reducing production costs owing to the excluded use of precious metals because the perovskite catalyst for NO oxidation can be used as a main component of an aftertreatment system for reducing NOx in exhaust gas of a leanburn gasoline engine or a diesel engine by producing the perovskite catalyst including silver (Ag) having the function of NO oxidation and excellent hydrothermal stability. The perovskite catalyst for NO oxidation is the core technology of an aftertreatment system for vehicle exhaust gas which can be used for an eco-friendly low-pollution vehicle to react to environmental restrictions in the WTO system.
