(57) [Abstract] The present invention relates to a method for decomposing and removing nitrogen oxides. [Structure] A reducing agent is added to exhaust gas containing nitrogen oxides, and 1 to 5% by weight of nitrogen, 3 to 30% by weight of oxygen, and 40% of carbon are added. ~ 95 wt% and average pore radius 15-30 Å, Perforated mesopores are at least 50% by volume based on the total volume Nitrogen oxides are reduced and removed in the presence of a specific activated carbon material occupying the same. |
