The invention relates to a preparation method of a flue gas synergistic denitration demercuration catalyst and the catalyst, and the preparation method comprises the following steps: s1, preparing raw materials, wherein the raw materials comprise a titanium dioxide carrier and active components, the active components comprise vanadium-containing compounds, tungsten-containing compounds, metal compounds or metal particles, and metal elements in the metal compounds or the metal particles are one or more of cerium, cobalt, manganese, niobium and zirconium elements; s2, dissolving the raw materials in the step S1 in a solvent and mixing to obtain a mixture; s3, performing extrusion molding on the mixture obtained in the step S2, and drying and roasting to obtain the catalyst. According to the invention, the titanium dioxide carrier and the active component are mixed, and one or more metal compounds or metal particles are added at the same time, so that the denitration performance of the catalyst is improved, and the catalyst has higher synergistic mercury oxidation removal performance; the catalyst belongs to a synergistic denitration and demercuration catalyst for controlling waste gas pollutants, and nitrogen-containing oxides and elemental mercury in flue gas are efficiently removed. |
