DUAL FUNCTIONAL CATALYSTS FOR DECOMPOSITION AND OXIDATION OF NITROGEN MONOXIDE, MIXED CATALYSTS FOR EXHAUST-GAS REDUCING DEVICE INCLUDING THE SAME, AND PREPARATION METHOD THEREOF

摘要

The present invention relates to: catalysts for simultaneous removal of nitrogen oxide and particulate material which have dual functions of decomposition and oxidation of nitrogen monoxide capable of preparation of nitrogen dioxide; mixed catalysts for a device for reducing exhaust-gas from diesel vehicles which include catalysts for simultaneous removal of nitrogen oxide and particulate material; and the preparation method thereof. The catalysts and mixed catalysts according to the invention are applicable to the device for reducing pollutants contained in the exhaust-gas from diesel vehicles and an exhaust-gas purifying system including the same.
