The present invention relates to a process for preparing a catalyst for the removal of nitrogen oxides, comprising the steps of: dissolving a cobalt precursor and a nickel precursor on an aqueous solution; Mixing the precursor with an aluminum metal oxide; (Co, Ni) Al 2 O 4 for removal of nitrogen oxides, Since the durability of the toxicity of the conventional catalyst to sulfur oxides is improved by providing the catalyst production method, the lifetime of the catalyst is increased, and since the catalyst having the spinel structure can increase the durability against sulfur oxides, (Co, Ni) Al 2 O 4 type catalyst. The present invention relates to a method for producing a catalyst of the present invention. |
