  • Mixed metal oxide catalyst for decomposition of nitrogen oxides
    Patent number: 9352303
    Abstract: The present invention relates to a mixed metal oxide catalyst in which a hydrotalcite precursor containing an alkali metal is impregnated or intercalated with a nonprecious metal, a method of manufacturing the same, and a method of decomposing nitrogen oxide using the mixed metal oxide catalyst. The mixed metal oxide catalyst has excellent catalytic activity because it can decompose NOx, N2O or a mixture thereof even at low temperature, and is economical because it does not use a precious metal.
    Type: Grant

  • Method for adsorbing and decomposing lean nitrogen oxide using a mixed metal oxide catalyst
    Patent number: 8512662
    Abstract: The present invention relates to a method of adsorbing and reducing nitrogen oxides using a mixed metal oxide catalyst, and more particularly, to a method of improving the efficiency of adsorption and desorption of nitrogen oxides using a mixed metal oxide catalyst prepared from a hydrotalcite precursor. According to the invention, NOx and N2O, which coexist with oxygen (O2) known to be very difficult to reduce and decompose, are efficiently decomposed by adsorbing and separating NOx and N2O from oxygen and then decomposing the adsorbed NOx and N2O using a reducing agent.
