Zusammenfassung:The invention relates to the field of SCR (Selective Catalytic Reduction) denitration catalysts, in particular to an SCR denitration catalyst for synergistically removing dioxin and a preparation method of the SCR denitration catalyst. Comprising the following raw materials: modified anatase titanium dioxide, a ZSM-5 molecular sieve, soluble cerium salt, soluble cobalt salt, 4-aminobenzimidazole, deionized water, an ammonium metavanadate-monoethanolamine solution, ammonium heptamolybdate, short glass fibers, a pore forming agent, silica sol, PEG, CMC, PEO and stearic acid. The modified anatase titanium dioxide is obtained by pre-reacting anatase titanium dioxide with polyphosphoric acid and then carrying out titanate surface modification. The prepared heterogeneous honeycomb catalyst has high-selectivity cracking and removal effects on dioxin, and shows more excellent denitration performance and water resistance. 本发明涉及SCR脱硝催化剂领域,尤其涉及一种协同脱除二噁英的SCR脱硝催化剂及其制备方法,包括以下原料:改性锐钛型钛白粉、ZSM-5分子筛、可溶性铈盐、可溶性钴盐、4-氨基苯并咪唑、去离子水、偏
