Zusammenfassung: | The present invention in particular relates to the field of waste gas treatment. Disclosed are a sulfur poisoning-resistant catalyst for catalytic combustion, a preparation method therefor, and a use thereof. According to the preparation method for a sulfur poisoning-resistant catalyst for catalytic combustion provided by the present invention, a specific secondary metal and a precious metal are reduced and uniformly dispersed by employing a polyol reduction method, the two metals are loaded on a catalyst carrier by employing wet impregnation, and the two metals may be mutually dependent and form an active interface. On the basis that a secondary metal sulfate has higher thermal stability, a sulfide in an industrial organic waste gas more easily combines with the secondary metal, and thus, in the sulfur poisoning-resistant catalyst for catalytic combustion prepared by the preparation method provided by the present invention, the secondary metal may play a role in protecting the precious metal from sulfur pois |
