The invention discloses a sulfur-resistant Ce-Mn-Zr catalyst, and a preparation method and application thereof. The Ce-Mn-Zr catalyst contains ZrO as a transition metal 2 、MnO 2 And CeO 2 . The Ce-Mn-Zr catalyst is obtained by doping Zr, and the dispersity of active sites of the catalyst is improved by utilizing the stabilizing effect of Zr on the size of the catalyst and the cluster inhibiting effect of Zr, so that more active sites are exposed to delay the poisoning process of the catalyst. In addition, the Ce-Mn-Zr catalyst has higher sulfur resistance and can be used for treating SO 2 And in the existing condition, SCR denitration work is carried out for a long time. |
