PURPOSE:To develop a denitration catalyst capable of preventing the generation of N2O during the decomposition of NOx by shifting the active region of the catalyst to a higher temperature range in which the N2O generation is suppressed. CONSTITUTION:A catalyst for purifying exhaust gas by removing NOx in the exhaust gas containing excessive oxygen is prepared by heat-treating an alumina support carrying platinum at 600-800 deg.C in the atmosphere. |
