The present invention relates to a deNOx catalyst for removing nitrogen oxides by selective ammonia reduction and a method for preparing the same, and more specifically, to a titania-based deNOx catalyst supported with porous flake magnesium oxide, the deNOx catalyst prepared by supporting a magnesium oxide-dispersed slurry in the form of a porous flake on a titania-based catalyst, and a method for preparing the same. The deNOx catalyst of the present invention has improved alkali resistance and deNOx properties, thereby solving the problem of alkali metal poisoning. 본 발명은 암모니아 선택적 환원법에 의한 질소산화물 제거용 탈질촉매 및 그의 제조 방법에 관한 것으로, 더욱 상세하게는 다공판상체(porous flake) 형태의 마그네슘산화물 분산 슬러리를 티타니아계 촉매에 담지하여 제조되는, 다공판상체 마그네슘산화물이 담지된 티타니아계 탈질촉매 및 그의 제조 방법에 관한 것이다. 본 발명의 탈질촉매는 내알칼리성 탈질 특성이 향상됨으로써, 알칼리 금속의 피독 문제를 해결할 수 있다.
