Abstract: The present invention discloses a low-temperature nitrogen oxide adsorber based on a metal oxide-impregnated platinum/gamma-alumina catalyst and a method for preparing the same. According to the present invention, the present invention provides a method for preparing a passive nitrogen oxide adsorber for removing nitrogen oxide from a diesel engine, comprising the steps of: (a) impregnating a gamma-alumina support with an aqueous solution of the noble metal catalyst precursor and drying it repeatedly up to a preset number of times; (b) obtaining a noble metal/gamma-alumina catalyst by sintering at a predetermined temperature after step (a) is completed; (c) impregnating the noble metal/gamma-alumina catalyst with an aqueous solution of a metal oxide precursor and drying it repeatedly up to a preset number of times; and (d) preparing a passive nitrogen oxide adsorber composed of Ax-B/γ-alumina by sintering at a predetermined temperature after step (c) is completed, wherein the A is a noble metal catalyst, x is the mass percent of the noble metal catalyst, and the B is a metal.
