Integrated honeycomb SCR (selective catalytic reduction) catalyst for low-temperature smoke denitration and preparation method of catalyst

The invention discloses an integrated honeycomb SCR (selective catalytic reduction) catalyst for low-temperature smoke denitration and a preparation method of the catalyst, wherein the integrated honeycomb SCR catalyst comprises substrates, active elements and additives; the substrates are TiO2 and ZSM-5 molecular sieve powder; the active elements comprise ZrO2, MnO2, Fe2O3 and CeO2. The catalyst provided by the invention not only has higher catalytic activity at a low temperature (120 DEG C), but also has a good waterproof property and a higher practical application value in engineering.
