Beschreibung
Zusammenfassung:	본 발명은 정지기동(on/off) 시 저온에서 발생하는 이산화질소(NO2)의 비율이 높은 질소산화물(NOx) 배출 조건에서도 우수한 NOx 제거효율을 갖는 탈질촉매 및 그 용도에 관한 것이다. The present invention relates to a denitration catalyst and use thereof, the denitration catalyst having excellent nitrogen oxide (NOx) removal efficiency even under NOx emission conditions in which the proportion of nitrogen dioxide (NO2) generated at low temperature at starting/stopping (on/off) is high. The denitration catalyst of the present invention is for removing nitrogen oxide (NOx) from exhaust gas in which the proportion of nitrogen dioxide (NO2) among NOx is 10-100 volume%, wherein the denitration catalyst includes at least a portion of the structure Mn(VO2)2.
