Abstract: The present invention relates to a configuration method of a multifunctional particulate filter (MFPF), capable of reducing the content of particulate material (PM), carbon monoxide (CO) and hydrocarbons (HC), and increasing the content of nitrogen dioxide (NO2). The MFPF may coat zeolite and an oxidation catalyst on both exhaust gas intake/discharge sides simultaneously, so as to minimize the slippage of HC and generate high-concentration NO2.

Abstract: Disclosed are a bifunctional catalyst for simultaneously removing nitrogen oxide and particulate matters, capable of decomposing nitrogen monoxide and generating nitrogen dioxide through oxidation of nitrogen monoxide, a composite catalyst including the catalyst for simultaneously removing nitrogen oxide and particulate matters used for an apparatus to decrease exhaust gas of diesel vehicles, and a method for preparation thereof. The catalyst and the composite catalyst can be used in a device for reducing exhaust gas contaminants mounted on a diesel vehicle and an exhaust gas purification system comprising the device.
