  • Publication number: 20100075842
    Abstract: Disclosed herein is a method of producing a catalyst for storing nitrogen oxides, including: supporting a potassium oxide on alumina, which serves as a support, and then calcining the alumina supported with the potassium oxide at a high temperature, thus chemically bonding potassium oxide with the alumina. The method is advantageous in that a catalyst for storing nitrogen oxides, having high nitrogen oxide storage capacity and excellent hydrothermal stability, can be produced at low cost through a simple process.
