| 摘要 |
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.
