Provided is a high-performance catalyst for cleaning up nitrogen oxides, which has excellent initial performance and durability, and which is not liable to deteriorate over time and thus overcomes the drawbacks of conventional silver-loaded alumina catalysts with which the nitrogen oxides are reduced using ethanol. The catalyst, which cleans up the nitrogen oxides in exhaust gases using alcohol as a reducing agent, contains alumina, aluminum sulfate and silver as the main components. |
